| <p><font size=+1><b>DESCRIPTION </b></font><br> |
| |
| <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> |
| |
| <i>Rdproto</i> reads and interprets the named <i>proto</i> file relative to |
| the root directory <i>root</i>. |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| Each line of the <i>proto</i> file specifies a file to copy. Blank lines |
| and lines beginning with <tt><font size=+1>#</font></tt> are ignored. Indentation (usually tabs) |
| is significant, with each level of indentation corresponding to |
| a level in the file tree. Fields within a line are separated by |
| white space. The first field is the last path element in the destination |
| file tree. The second field specifies the permissions. The third |
| field is the owner of the file, and the fourth is the group owning |
| the file. The fifth field is the name of the file from which to |
| copy; this file is read from the current name space, not the source |
| file tree. All fields except the first are optional. Specifying |
| <tt><font size=+1>−</font></tt> for |
| permissions, owner, or group causes <i>rdproto</i> to fetch the corresponding |
| information from the file rather than override it. (This is the |
| default behavior when the fields are not present; explicitly specifying |
| <tt><font size=+1>−</font></tt> is useful when one wishes to set, say, the file owner without |
| setting the permissions.) |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| Names beginning with a <tt><font size=+1>$</font></tt> are expanded as environment variables. |
| If the first file specified in a directory is <tt><font size=+1>*</font></tt>, all of the files |
| in that directory are considered listed. If the first file is |
| <tt><font size=+1>+</font></tt>, all of the files are copied, and all subdirectories are recursively |
| considered listed. All files are considered relative to <i>root</i>. |
| |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| For each file named by the <i>proto</i>, <i>enm</i> is called with <i>new</i> pointing |
| at the name of the file (without the root prefix), <i>old</i> pointing |
| at the name of the source file (with the root prefix, when applicable), |
| and <i>Dir</i> at the desired directory information for the new file. |
| Only the <tt><font size=+1>name</font></tt>, <tt><font size=+1>uid</font></tt>, <tt><font size=+1>gid</font></tt>, <tt><font size=+1>mode</font></tt>, <tt><font size=+1>mtime</font></tt>, and <tt><font size=+1>length</font></tt> fields |
| are guaranteed to be valid. The argument <i>a</i> is the same argument |
| passed to <i>rdproto</i>; typically it points at some extra state used |
| by the enumeration function. |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| When files or directories do not exist or cannot be read by <i>rdproto</i>, |
| it formats a warning message, calls <i>warn</i>, and continues processing; |
| if <i>warn</i> is nil, <i>rdproto</i> prints the warning message to standard |
| error. |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| <i>Rdproto</i> returns zero if <i>proto</i> was processed, –1 if it could not |
| be opened.<br> |
