| |
| <i>Cleanname</i> takes a <i>filename</i> and by lexical processing only returns |
| the shortest string that names the same (possibly hypothetical) |
| file. It eliminates multiple and trailing slashes, and it lexically |
| interprets <tt><font size=+1>.</font></tt> and <tt><font size=+1>..</font></tt> directory components in the name. The string |
| is overwritten in place. |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| The shortest string <i>cleanname</i> can return is two bytes: the null-terminated |
| string <tt><font size=+1>"."</font></tt>. Therefore <i>filename</i> must contain room for at least two |
| bytes.<br> |
