<h3><font color=#C00040>Windows95 - LONG FILENAME - GET CANONICAL LONG FILENAME OR PATH</font></h3>

AX = 7160h

|
|

DS:SI -> ASCIZ short filename or path

|
|
<p><b>Return:</b><br>CF set on error
|
|
AX = error code
|
|
02h invalid component in directory path or drive letter only
|
|
03h malformed path or invalid drive letter
|

ES:DI buffer unchanged

|
|
ES:DI buffer filled with qualified long name (can contain

lowercase letters)
|
|
</PRE>
|
|
<p><b>Desc:</b>
|
|
Determine the canonical name of the specified filename or path,
|
|
corresponding to the undocumented TRUENAME command in COMMAND.COM
|
|
<p><b>BUGS:</b>
|
|
Even though the maximum length of a complete long pathname is 260
|
|
characters, Windows95 returns CF set/AX=0003h even if the file
|
|
exists whenever the full pathname is more than 255 characters.
|
|
Windows95 incorrectly treats filenames where the first two characters
|
|
after the drive letter and colon are both slashes (either forward
|
|
or backward) as a UNC (network name) and requires several seconds
|
|
to attempt to resolve the name before returning an unchanged
|
|
string
