I don't see where the traces for DOSFS_FindUnixName come from (except
the first one). Did you added them yourself?
Else, I don't think it's the \" which cause problem. DOSFS_ReadDir (and
others before it) are able to locate the proper directory (and
DOSFS_ReadDir enumerates it's content correctly). The problem seems to
come from this:
In DOSFS_FindUnixName:
name is "C:\Programme\Gemeinsame Dateien\Nokia\NCLTools\NclConf.cpl",
with the quotes;
DOSFS_ToDosFCBFormat returns FALSE (and then dos_name[0]=0) because
the first character of its argument is a " (and thus an
INVALID_DOS_CHARS), but it doesn't matter;
The DOSFS_OpenDir works correctly, with the proper Unix path;
The DOSFS_ReadDir loop cycles through the files in that dir,
returning (in long_name) the different files it finds (*without* any
path component);
long_name is then tested if it's the same length as the (minimum
between the position of the first backslash in name and the length of
name), which is 3 in this example, so of course it never matches and you
get the final warning in DOSFS_FindUnixName.
Relevant code of DOSFS_FindUnixName:
LPCWSTR p = strchrW( name, '/' );
int len = p ? (int)(p - name) : strlenW(name);
if ((p = strchrW( name, '\\' ))) len = min( (int)(p - name), len );
and
while ((ret = DOSFS_ReadDir( dir, &long_name, &short_name )))
{
/* Check against Unix name */
if (len == strlenW(long_name))
{
if (!ignore_case)
{
if (!strncmpW( long_name, name, len )) break;
}
else
{
if (!strncmpiW( long_name, name, len )) break;
}
}
Could somebody with more knowledge about the DOSFS_* functions can tell
if that's how DOSFS_FindUnixName is supposed to react (fail if name
contains a path)? If it is indeed the case, then it's upper the call
chain that there's a problem.
Call chain:
LoadLibraryA->MODULE_LoadLibraryExA
MODULE_LoadLibraryExA->SearchPathA
SearchPathA->SearchPathW
SearchPathW->DIR_SearchPath
DIR_SearchPath->DOSFS_GetFullName
DOSFS_GetFullName->DOSFS_FindUnixName
I'll try to go further with Nokia PC Suite 4.06.
Oh, and could you create a bug in bugzilla for this?
