<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>

    This library implements a parser for HTML 4.0 documents. The parsed
    HTML is converted into an intermediate representation that describes
    how the formatted HTML should be laid out. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <i>Parsehtml</i> parses an entire HTML document contained in the buffer
    <i>data</i> and having length <i>datalen</i>. The URL of the document should
    be passed in as <i>src</i>. <i>Mtype</i> is the media type of the document,
    which should be either <tt><font size=+1>TextHtml</font></tt> or <tt><font size=+1>TextPlain</font></tt>. The character set
    of the document is described in <i>chset</i>, which can be
    one of <tt><font size=+1>US_Ascii</font></tt>, <tt><font size=+1>ISO_8859_1</font></tt>, <tt><font size=+1>UTF_8</font></tt> or <tt><font size=+1>Unicode</font></tt>. The return value
    is a linked list of <tt><font size=+1>Item</font></tt> structures, described in detail below.
    As a side effect, <tt><font size=+1>*</font></tt><i>pdi</i> is set to point to a newly created <tt><font size=+1>Docinfo</font></tt>
    structure, containing information pertaining to the entire document.
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    The library expects two allocation routines to be provided by
    the caller, <tt><font size=+1>emalloc</font></tt> and <tt><font size=+1>erealloc</font></tt>. These routines are analogous
    to the standard malloc and realloc routines, except that they
    should not return if the memory allocation fails. In addition,
    <tt><font size=+1>emalloc</font></tt> is required to zero the memory. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    For debugging purposes, <i>printitems</i> may be called to display the
    contents of an item list; individual items may be printed using
    the <tt><font size=+1>%I</font></tt> print verb, installed on the first call to <i>parsehtml</i>. <i>validitems</i>
    traverses the item list, checking that all of the pointers are
    valid. It returns <tt><font size=+1>1</font></tt> is everything is ok, and <tt><font size=+1>0</font></tt> if an error was
    found. Normally, one would not call these routines directly. Instead,
    one sets the global variable <i>dbgbuild</i> and the library calls them
    automatically. One can also set <i>warn</i>, to cause the library to
    print a warning whenever it finds a problem with the input document,
    and <i>dbglex</i>, to print debugging information in the
    lexer. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    When an item list is finished with, it should be freed with <i>freeitems</i>.
    Then, <i>freedocinfo</i> should be called on the pointer returned in
    <tt><font size=+1>*</font></tt><i>pdi</i>. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <i>Dimenkind</i> and <i>dimenspec</i> are provided to interpret the <tt><font size=+1>Dimen</font></tt> type,
    as described in the section <i>Dimension Specifications</i>. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    Frame target names are mapped to integer ids via a global, permanent
    mapping. To find the value for a given name, call <i>targetid</i>, which
    allocates a new id if the name hasn&#8217;t been seen before. The name
    of a given, known id may be retrieved using <i>targetname</i>. The library
    predefines <tt><font size=+1>FTtop</font></tt>, <tt><font size=+1>FTself</font></tt>, <tt><font size=+1>FTparent</font></tt> and
    <tt><font size=+1>FTblank</font></tt>. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    The library handles all text as Unicode strings (type <tt><font size=+1>Rune*</font></tt>).
    Character set conversion is provided by <i>fromStr</i> and <i>toStr</i>. <i>FromStr</i>
    takes <i>n</i> Unicode characters from <i>buf</i> and converts them to the character
    set described by <i>chset</i>. <i>ToStr</i> takes <i>n</i> bytes from <i>buf</i>, interpretted
    as belonging to character set <i>chset</i>, and converts
    them to a Unicode string. Both routines null-terminate the result,
    and use <tt><font size=+1>emalloc</font></tt> to allocate space for it.<br>
    <p><font size=+1><b>Items     </b></font><br>
    The return value of <i>parsehtml</i> is a linked list of variant structures,
    with the generic portion described by the following definition:
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Item Item;<br>
    struct Item<br>

    </table>
    };<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    The field <tt><font size=+1>next</font></tt> points to the successor in the linked list of items,
    while <tt><font size=+1>width</font></tt>, <tt><font size=+1>height</font></tt>, and <tt><font size=+1>ascent</font></tt> are intended for use by the caller
    as part of the layout process. <tt><font size=+1>Anchorid</font></tt>, if non-zero, gives the
    integer id assigned by the parser to the anchor that this item
    is in (see section <i>Anchors</i>). <tt><font size=+1>State</font></tt> is a collection of
    flags and values described as follows: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>enum<br>
    {<br>

    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    <tt><font size=+1>IFbrk</font></tt> is set if a break is to be forced before placing this item.
    <tt><font size=+1>IFbrksp</font></tt> is set if a 1 line space should be added to the break
    (in which case <tt><font size=+1>IFbrk</font></tt> is also set). <tt><font size=+1>IFnobrk</font></tt> is set if a break is
    not permitted before the item. <tt><font size=+1>IFcleft</font></tt> is set if left floats should
    be cleared (that is, if the list of pending left floats should
    be placed) before this item is placed, and <tt><font size=+1>IFcright</font></tt> is set for
    right floats. In both cases, IFbrk is also set. <tt><font size=+1>IFwrap</font></tt> is set
    if the line containing this item is allowed to wrap. <tt><font size=+1>IFhang</font></tt> is
    set if this item hangs into the left indent. <tt><font size=+1>IFrjust</font></tt> is set if
    the line containing this item should be right justified, and <tt><font size=+1>IFcjust</font></tt>
    is
    set for center justified lines. <tt><font size=+1>IFsmap</font></tt> is used to indicate that
    an image is a server-side map. The low 8 bits, represented by
    <tt><font size=+1>IFhangmask</font></tt>, indicate the current hang into left indent, in tenths
    of a tabstop. The next 8 bits, represented by <tt><font size=+1>IFindentmask</font></tt> and
    <tt><font size=+1>IFindentshift</font></tt>, indicate the current indent in tab
    stops. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    The field <tt><font size=+1>genattr</font></tt> is an optional pointer to an auxiliary structure,
    described in the section <i>Generic Attributes</i>. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    Finally, <tt><font size=+1>tag</font></tt> describes which variant type this item has. It can
    have one of the values <tt><font size=+1>Itexttag</font></tt>, <tt><font size=+1>Iruletag</font></tt>, <tt><font size=+1>Iimagetag</font></tt>, <tt><font size=+1>Iformfieldtag</font></tt>,
    <tt><font size=+1>Itabletag</font></tt>, <tt><font size=+1>Ifloattag</font></tt> or <tt><font size=+1>Ispacertag</font></tt>. For each of these values,
    there is an additional structure defined, which includes Item
    as an unnamed initial substructure,
    and then defines additional fields. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    Items of type <tt><font size=+1>Itexttag</font></tt> represent a piece of text, using the following

    Here <tt><font size=+1>s</font></tt> is a null-terminated Unicode string of the actual characters
    making up this text item, <tt><font size=+1>fnt</font></tt> is the font number (described in
    the section <i>Font Numbers</i>), and <tt><font size=+1>fg</font></tt> is the RGB encoded color for
    the text. <tt><font size=+1>Voff</font></tt> measures the vertical offset from the baseline;
    subtract <tt><font size=+1>Voffbias</font></tt> to get the actual value (negative values
    represent a displacement down the page). The field <tt><font size=+1>ul</font></tt> is the underline
    style: <tt><font size=+1>ULnone</font></tt> if no underline, <tt><font size=+1>ULunder</font></tt> for conventional underline,

    Here <tt><font size=+1>imsrc</font></tt> is the URL of the image source, <tt><font size=+1>imwidth</font></tt> and <tt><font size=+1>imheight</font></tt>,
    if non-zero, contain the specified width and height for the image,
    and <tt><font size=+1>altrep</font></tt> is the text to use as an alternative to the image,
    if the image is not displayed. <tt><font size=+1>Map</font></tt>, if set, points to a structure
    describing an associated client-side image map.
    <tt><font size=+1>Ctlid</font></tt> is reserved for use by the application, for handling animated
    images. <tt><font size=+1>Align</font></tt> encodes the alignment specification of the image.
    <tt><font size=+1>Hspace</font></tt> contains the number of pixels to pad the image with on
    either side, and <tt><font size=+1>Vspace</font></tt> the padding above and below. <tt><font size=+1>Border</font></tt> is
    the width of the border to draw around the
    image. <tt><font size=+1>Nextimage</font></tt> points to the next image in the document (the
    head of this list is <tt><font size=+1>Docinfo.images</font></tt>). 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    For items of type <tt><font size=+1>Iformfieldtag</font></tt>, the following structure is defined:
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>struct Iformfield<br>

    This adds a single field, <tt><font size=+1>formfield</font></tt>, which points to a structure
    describing a field in a form, described in section <i>Forms</i>. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    For items of type <tt><font size=+1>Itabletag</font></tt>, the following structure is defined:

    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    <tt><font size=+1>Table</font></tt> points to a structure describing the table, described in
    the section <i>Tables</i>. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    For items of type <tt><font size=+1>Ifloattag</font></tt>, the following structure is defined:

    </table>
    };<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    The <tt><font size=+1>item</font></tt> points to a single item (either a table or an image)
    that floats (the text of the document flows around it), and <tt><font size=+1>side</font></tt>
    indicates the margin that this float sticks to; it is either <tt><font size=+1>ALleft</font></tt>
    or <tt><font size=+1>ALright</font></tt>. <tt><font size=+1>X</font></tt> and <tt><font size=+1>y</font></tt> are reserved for use by the caller; these
    are typically used for the coordinates of the top of the float.
    <tt><font size=+1>Infloats</font></tt> is used by the caller to keep track of whether it has
    placed the float. <tt><font size=+1>Nextfloat</font></tt> is used by the caller to link together
    all of the floats that it has placed. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    For items of type <tt><font size=+1>Ispacertag</font></tt>, the following structure is defined:
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>struct Ispacer<br>

    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    <tt><font size=+1>Spkind</font></tt> encodes the kind of spacer, and may be one of <tt><font size=+1>ISPnull</font></tt> (zero
    height and width), <tt><font size=+1>ISPvline</font></tt> (takes on height and ascent of the
    current font), <tt><font size=+1>ISPhspace</font></tt> (has the width of a space in the current
    font) and <tt><font size=+1>ISPgeneral</font></tt> (for all other purposes, such as between
    markers and lists).
    <p><font size=+1><b>Generic Attributes    </b></font><br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    The genattr field of an item, if non-nil, points to a structure
    that holds the values of attributes not specific to any particular
    item type, as they occur on a wide variety of underlying HTML
    tags. The structure is as follows: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Genattr Genattr;<br>
    struct Genattr<br>

    </table>
    };<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    Fields <tt><font size=+1>id</font></tt>, <tt><font size=+1>class</font></tt>, <tt><font size=+1>style</font></tt> and <tt><font size=+1>title</font></tt>, when non-nil, contain values
    of correspondingly named attributes of the HTML tag associated
    with this item. <tt><font size=+1>Events</font></tt> is a linked list of events (with corresponding
    scripted actions) associated with the item: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct SEvent SEvent;<br>

    script.<br>
    <p><font size=+1><b>Dimension Specifications    </b></font><br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    Some structures include a dimension specification, used where
    a number can be followed by a <tt><font size=+1>%</font></tt> or a <tt><font size=+1>*</font></tt> to indicate percentage
    of total or relative weight. This is encoded using the following
    structure: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Dimen Dimen;<br>
    struct Dimen<br>
    {<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>

        int kindspec;<br>
        
    </table>
    };<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    Separate kind and spec values are extracted using <i>dimenkind</i> and
    <i>dimenspec</i>. <i>Dimenkind</i> returns one of <tt><font size=+1>Dnone</font></tt>, <tt><font size=+1>Dpixels</font></tt>, <tt><font size=+1>Dpercent</font></tt> or
    <tt><font size=+1>Drelative</font></tt>. <tt><font size=+1>Dnone</font></tt> means that no dimension was specified. In all
    other cases, <i>dimenspec</i> should be called to find the absolute number
    of pixels, the percentage of total, or the
    relative weight.<br>
    <p><font size=+1><b>Background Specifications    </b></font><br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    It is possible to set the background of the entire document, and
    also for some parts of the document (such as tables). This is
    encoded as follows: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Background Background;<br>
    struct Background<br>
    {<br>

        Rune* image;<br>
        int &nbsp;&nbsp;&nbsp;&nbsp;color;<br>
        
    </table>
    };<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    <tt><font size=+1>Image</font></tt>, if non-nil, is the URL of an image to use as the background.
    If this is nil, <tt><font size=+1>color</font></tt> is used instead, as the RGB value for a
    solid fill color.<br>
    <p><font size=+1><b>Alignment Specifications    </b></font><br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    Certain items have alignment specifiers taken from the following
    enumerated type: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>enum<br>
    {<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>

        ALnone = 0, ALleft, ALcenter, ALright, ALjustify,<br>
        ALchar, ALtop, ALmiddle, ALbottom, ALbaseline<br>
        
    </table>
    };<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    These values correspond to the various alignment types named in
    the HTML 4.0 standard. If an item has an alignment of <tt><font size=+1>ALleft</font></tt> or
    <tt><font size=+1>ALright</font></tt>, the library automatically encapsulates it inside a float
    item. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    Tables, and the various rows, columns and cells within them, have
    a more complex alignment specification, composed of separate vertical
    and horizontal alignments: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Align Align;<br>

    <p><font size=+1><b>Font Numbers    </b></font><br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    Text items have an associated font number (the <tt><font size=+1>fnt</font></tt> field), which
    is encoded as <tt><font size=+1>style*NumSize+size</font></tt>. Here, <tt><font size=+1>style</font></tt> is one of <tt><font size=+1>FntR</font></tt>,
    <tt><font size=+1>FntI</font></tt>, <tt><font size=+1>FntB</font></tt> or <tt><font size=+1>FntT</font></tt>, for roman, italic, bold and typewriter font
    styles, respectively, and size is <tt><font size=+1>Tiny</font></tt>, <tt><font size=+1>Small</font></tt>, <tt><font size=+1>Normal</font></tt>, <tt><font size=+1>Large</font></tt> or
    <tt><font size=+1>Verylarge</font></tt>. The total number of possible
    font numbers is <tt><font size=+1>NumFnt</font></tt>, and the default font number is <tt><font size=+1>DefFnt</font></tt>
    (which is roman style, normal size).<br>

    The library builds two lists for all of the <tt><font size=+1>&lt;a&gt;</font></tt> elements (anchors)
    in a document. Each anchor is assigned a unique anchor id within
    the document. For anchors which are hyperlinks (the <tt><font size=+1>href</font></tt> attribute
    was supplied), the following structure is defined: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Anchor Anchor;<br>
    struct Anchor<br>

    <tt><font size=+1>Next</font></tt> points to the next anchor in the list (the head of this list
    is <tt><font size=+1>Docinfo.anchors</font></tt>). <tt><font size=+1>Index</font></tt> is the anchor id; each item within
    this hyperlink is tagged with this value in its <tt><font size=+1>anchorid</font></tt> field.
    <tt><font size=+1>Name</font></tt> and <tt><font size=+1>href</font></tt> are the values of the correspondingly named attributes
    of the anchor (in particular, href is the URL to go
    to). <tt><font size=+1>Target</font></tt> is the value of the target attribute (if provided)
    converted to a frame id. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    Destinations within the document (anchors with the name attribute

    Here, <tt><font size=+1>next</font></tt> points to the next field in the list. <tt><font size=+1>Ftype</font></tt> is the
    type of the field, which can be one of <tt><font size=+1>Ftext</font></tt>, <tt><font size=+1>Fpassword</font></tt>, <tt><font size=+1>Fcheckbox</font></tt>,
    <tt><font size=+1>Fradio</font></tt>, <tt><font size=+1>Fsubmit</font></tt>, <tt><font size=+1>Fhidden</font></tt>, <tt><font size=+1>Fimage</font></tt>, <tt><font size=+1>Freset</font></tt>, <tt><font size=+1>Ffile</font></tt>, <tt><font size=+1>Fbutton</font></tt>, <tt><font size=+1>Fselect</font></tt>
    or <tt><font size=+1>Ftextarea</font></tt>. <tt><font size=+1>Fieldid</font></tt> is a serial number for the field within
    the form. <tt><font size=+1>Form</font></tt> points back
    to the form containing this field. <tt><font size=+1>Name</font></tt>, <tt><font size=+1>value</font></tt>, <tt><font size=+1>size</font></tt>, <tt><font size=+1>maxlength</font></tt>,
    <tt><font size=+1>rows</font></tt> and <tt><font size=+1>cols</font></tt> each contain the values of corresponding attributes
    of the field, if present. <tt><font size=+1>Flags</font></tt> contains per-field flags, of which
    <tt><font size=+1>FFchecked</font></tt> and <tt><font size=+1>FFmultiple</font></tt> are defined. <tt><font size=+1>Image</font></tt> is only used for fields
    of type <tt><font size=+1>Fimage</font></tt>; it points to an
    image item containing the image to be displayed. <tt><font size=+1>Ctlid</font></tt> is reserved
    for use by the caller, typically to store a unique id of an associated
    control used to implement the field. <tt><font size=+1>Events</font></tt> is the same as the
    corresponding field of the generic attributes associated with
    the item containing this field. <tt><font size=+1>Options</font></tt> is only used by
    fields of type <tt><font size=+1>Fselect</font></tt>; it consists of a list of possible options
    that may be selected for that field, using the following structure:
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Option Option;<br>

    <tt><font size=+1>Next</font></tt> points to the next element in the list of tables. <tt><font size=+1>Tableid</font></tt>
    is a serial number for the table within the document. <tt><font size=+1>Rows</font></tt> is
    an array of row specifications (described below) and <tt><font size=+1>nrow</font></tt> is the
    number of elements in this array. Similarly, <tt><font size=+1>cols</font></tt> is an array
    of column specifications, and <tt><font size=+1>ncol</font></tt> the size of this array.
    <tt><font size=+1>Cells</font></tt> is a list of all cells within the table (structure described
    below) and <tt><font size=+1>ncell</font></tt> is the number of elements in this list. Note
    that a cell may span multiple rows and/or columns, thus <tt><font size=+1>ncell</font></tt>
    may be smaller than <tt><font size=+1>nrow*ncol</font></tt>. <tt><font size=+1>Grid</font></tt> is a two-dimensional array
    of cells within the table; the cell at row <tt><font size=+1>i</font></tt> and column <tt><font size=+1>j</font></tt> is
    <tt><font size=+1>Table.grid[i][j]</font></tt>. A cell that spans multiple rows and/or columns
    will be referenced by <tt><font size=+1>grid</font></tt> multiple times, however it will only
    occur once in <tt><font size=+1>cells</font></tt>. <tt><font size=+1>Align</font></tt> gives the alignment specification for
    the entire table, and <tt><font size=+1>width</font></tt> gives the requested width as a dimension
    specification. <tt><font size=+1>Border</font></tt>, <tt><font size=+1>cellspacing
    </font></tt>and <tt><font size=+1>cellpadding</font></tt> give the values of the corresponding attributes
    for the table, and <tt><font size=+1>background</font></tt> gives the requested background for
    the table. <tt><font size=+1>Caption</font></tt> is a linked list of items to be displayed as
    the caption of the table, either above or below depending on whether
    <tt><font size=+1>caption_place</font></tt> is <tt><font size=+1>ALtop</font></tt> or <tt><font size=+1>ALbottom</font></tt>.
    Most of the remaining fields are reserved for use by the caller,
    except <tt><font size=+1>tabletok</font></tt>, which is reserved for internal use. The type
    <tt><font size=+1>Lay</font></tt> is not defined by the library; the caller can provide its
    own definition. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    The <tt><font size=+1>Tablecol</font></tt> structure is defined for use by the caller. The library
    ensures that the correct number of these is allocated, but leaves
    them blank. The fields are as follows: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Tablecol Tablecol;<br>
    struct Tablecol<br>

    </table>
    };<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    The rows in the table are specified as follows: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Tablerow Tablerow;<br>
    struct Tablerow<br>

    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    <tt><font size=+1>Next</font></tt> is only used during parsing; it should be ignored by the
    caller. <tt><font size=+1>Cells</font></tt> provides a list of all the cells in a row, linked
    through their <tt><font size=+1>nextinrow</font></tt> fields (see below). <tt><font size=+1>Height</font></tt>, <tt><font size=+1>ascent</font></tt> and
    <tt><font size=+1>pos</font></tt> are reserved for use by the caller. <tt><font size=+1>Align</font></tt> is the alignment
    specification for the row, and <tt><font size=+1>background</font></tt> is the
    background to use, if specified. <tt><font size=+1>Flags</font></tt> is used by the parser;
    ignore this field. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    The individual cells of the table are described as follows:

    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    <tt><font size=+1>Next</font></tt> is used to link together the list of all cells within a table
    (<tt><font size=+1>Table.cells</font></tt>), whereas <tt><font size=+1>nextinrow</font></tt> is used to link together all
    the cells within a single row (<tt><font size=+1>Tablerow.cells</font></tt>). <tt><font size=+1>Cellid</font></tt> provides
    a serial number for the cell within the table. <tt><font size=+1>Content</font></tt> is a linked
    list of the items to be laid out within the cell. <tt><font size=+1>Lay
    </font></tt>is reserved for the user to describe how these items have been
    laid out. <tt><font size=+1>Rowspan</font></tt> and <tt><font size=+1>colspan</font></tt> are the number of rows and columns
    spanned by this cell, respectively. <tt><font size=+1>Align</font></tt> is the alignment specification
    for the cell. <tt><font size=+1>Flags</font></tt> is some combination of <tt><font size=+1>TFparsing</font></tt>, <tt><font size=+1>TFnowrap</font></tt>
    and <tt><font size=+1>TFisth</font></tt> or&#8217;d together. Here
    <tt><font size=+1>TFparsing</font></tt> is used internally by the parser, and should be ignored.
    <tt><font size=+1>TFnowrap</font></tt> means that the contents of the cell should not be wrapped
    if they don&#8217;t fit the available width, rather, the table should
    be expanded if need be (this is set when the nowrap attribute
    is supplied). <tt><font size=+1>TFisth</font></tt> means that the cell was created
    by the <tt><font size=+1>&lt;th&gt;</font></tt> element (rather than the <tt><font size=+1>&lt;td&gt;</font></tt> element), indicating that
    it is a header cell rather than a data cell. <tt><font size=+1>Wspec</font></tt> provides a
    suggested width as a dimension specification, and <tt><font size=+1>hspec</font></tt> provides
    a suggested height in pixels. <tt><font size=+1>Background</font></tt> gives a background specification
    for the individual cell. <tt><font size=+1>Minw</font></tt>, <tt><font size=+1>maxw</font></tt>,
    <tt><font size=+1>ascent</font></tt> and <tt><font size=+1>pos</font></tt> are reserved for use by the caller during layout.
    <tt><font size=+1>Row</font></tt> and <tt><font size=+1>col</font></tt> give the indices of the row and column of the top
    left-hand corner of the cell within the table grid.<br>
    <p><font size=+1><b>Client-side Maps    </b></font><br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    The library builds a list of client-side maps, headed by <tt><font size=+1>Docinfo.maps</font></tt>,
    and having the following structure: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Map Map;<br>
    struct Map<br>
    {<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>

        Map* &nbsp;&nbsp;&nbsp;next;<br>

    };<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    <tt><font size=+1>Next</font></tt> points to the next element in the list, <tt><font size=+1>name</font></tt> is the name
    of the map (use to bind it to an image), and <tt><font size=+1>areas</font></tt> is a list of
    the areas within the image that comprise the map, using the following
    structure: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Area Area;<br>
    struct Area<br>
    {<br>

    </table>
    };<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    <tt><font size=+1>Next</font></tt> points to the next element in the map&#8217;s list of areas. <tt><font size=+1>Shape</font></tt>
    describes the shape of the area, and is one of <tt><font size=+1>SHrect</font></tt>, <tt><font size=+1>SHcircle</font></tt>
    or <tt><font size=+1>SHpoly</font></tt>. <tt><font size=+1>Href</font></tt> is the URL associated with this area in its role
    as a hypertext link, and <tt><font size=+1>target</font></tt> is the target frame it should
    be loaded in. <tt><font size=+1>Coords</font></tt> is an array of coordinates for
    the shape, and <tt><font size=+1>ncoords</font></tt> is the size of this array (number of elements).<br>
    <p><font size=+1><b>Frames     </b></font><br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    If the <tt><font size=+1>Docinfo.kidinfo</font></tt> field is set, the document is a frameset.
    In this case, it is typical for <i>parsehtml</i> to return nil, as a
    document which is a frameset should have no actual items that
    need to be laid out (such will appear only in subsidiary documents).
    It is possible that items will be returned by a malformed
    document; the caller should check for this and free any such items.
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    The <tt><font size=+1>Kidinfo</font></tt> structure itself reflects the fact that framesets
    can be nested within a document. If is defined as follows: 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    <tt><font size=+1>typedef struct Kidinfo Kidinfo;<br>
    struct Kidinfo<br>
    {<br>

        Rune* &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;name;<br>
        int &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;marginw;<br>
        int &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;marginh;<br>
        int &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;framebd;<br>
        int &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;flags;<br>
        // fields for &quot;frameset&quot;<br>

    </table>
    };<br>
    
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    </font></tt>
    <tt><font size=+1>Next</font></tt> is only used if this structure is part of a containing frameset;
    it points to the next element in the list of children of that
    frameset. <tt><font size=+1>Isframeset</font></tt> is set when this structure represents a frameset;
    if clear, it is an individual frame. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    Some fields are used only for framesets. <tt><font size=+1>Rows</font></tt> is an array of dimension
    specifications for rows in the frameset, and <tt><font size=+1>nrows</font></tt> is the length
    of this array. <tt><font size=+1>Cols</font></tt> is the corresponding array for columns, of
    length <tt><font size=+1>ncols</font></tt>. <tt><font size=+1>Kidinfos</font></tt> points to a list of components contained
    within this frameset, each of which may be a
    frameset or a frame. <tt><font size=+1>Nextframeset</font></tt> is only used during parsing,
    and should be ignored. 
    <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
    
    The remaining fields are used if the structure describes a frame,
    not a frameset. <tt><font size=+1>Src</font></tt> provides the URL for the document that should
    be initially loaded into this frame. Note that this may be a relative
    URL, in which case it should be interpretted using the containing
    document&#8217;s URL as the base. <tt><font size=+1>Name</font></tt> gives the name of
    the frame, typically supplied via a name attribute in the HTML.
    If no name was given, the library allocates one. <tt><font size=+1>Marginw</font></tt>, <tt><font size=+1>marginh</font></tt>
    and <tt><font size=+1>framebd</font></tt> are the values of the marginwidth, marginheight and
    frameborder attributes, respectively. <tt><font size=+1>Flags</font></tt> can contain some combination
