So what does that mean? The code is OK there and it isn't reached on systems where readdir_r returns 0 for success? I'm not quite sure what to do with this bug report. We either need to differentiate between Solaris and HPUX readdir_r or ignore the return value of that system call, as the semantics differ. Solaris return non-zero on success whereas HPUX returns zero. This could be achieved by setting entry-d_name[0] to NUL before the system call and assume that it failed, if the system call does not change the contents of d_name. - Sascha Experience IRCG http://schumann.cx/http://schumann.cx/ircg -- PHP Development Mailing List http://www.php.net/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Larry,
You are right if this code refers to the POSIX semantics of readdir_r.
However, this code is in #if defined(HAVE_OLD_READDIR_R) and I don't know
what is meant by old readdir_r (different semantics?).
Sascha? Can you shed some light on this?

Description: readdir doesn't work see Bug ID # 9058
Hi,
i think this is the problem (reentrancy.c)
int ret;
errno = 0;
ret = readdir_r(dirp, entry);
if (!ret || errno != 0) {
*result = NULL;
} else {
*result = entry;
}
return errno;
thr return value of readdir_r is 0 on success, so the above
will return NULL on success. The line should be something like
if (ret != 0 || errno != 0) {

Greetings,
I have unknowlingly followed the same path that Brian has in bug report #
9058. Namely, HP-UX 10.20, gcc version 2.95, PHP compiled many different
ways but latley -
./configure --enable-libgcc --with-apxs=/usr/local/apache/bin/apxs
--with-mysql=/usr/local/mysql --disable-posix
My application seems to work OK with the execption of no files listed from
a readdir call. The example code from readdir returns -
Directory handle: Resource id #1 Files:
and no file names.
Please let me know if there is anything I can do.
