I take a slighly different approach in mu:
/* if the file system does not support entry->d_type, we add it ourselves
* this is slower (extra stat) but at least it works
*/
static gboolean
_set_dtype (const char* path, struct dirent *entry)
{
struct stat statbuf;
char fullpath[4096];
snprintf (fullpath, sizeof(fullpath), "%s%c%s",
path, G_DIR_SEPARATOR, entry->d_name);
if (stat (fullpath, &statbuf) != 0) {
g_warning ("stat failed on %s: %s", fullpath,
strerror(errno));
return FALSE;
}
/* we only care about dirs, regular files and links */
if (S_ISREG (statbuf.st_mode))
entry->d_type = DT_REG;
else if (S_ISDIR (statbuf.st_mode))
entry->d_type = DT_DIR;
else if (S_ISLNK (statbuf.st_mode))
entry->d_type = DT_LNK;
return TRUE;
}
and then in some other places:
/* handle FSs that don't support entry->d_type */
if (entry->d_type == DT_UNKNOWN)
_set_dtype (dirname, entry);
Note, that is untested as of yet.
Best wishes,
Dirk.
