i hate glob()

ok, anyone here with experience using glob?  On occasion it returns -1, which isn't a defined return code, so I have no clue where this comes from... adding an errofunc doesn't help...

Re: i hate glob()

I have no clue, but I found this..

If glob succeeds, it returns 0. Otherwise, it returns one of these error codes:

GLOB_ABORTED
    There was an error opening a directory, and you used the flag GLOB_ERR or your specified errfunc returned a nonzero value. for an explanation of the GLOB_ERR flag and errfunc.
GLOB_NOMATCH
    The pattern didn't match any existing files. If you use the GLOB_NOCHECK flag, then you never get this error code, because that flag tells glob to pretend that the pattern matched at least one file.
GLOB_NOSPACE
    It was impossible to allocate memory to hold the result.

Re: i hate glob()

yeah, from the header:

/* Error returns from `glob'.  */
#define  GLOB_NOSPACE   1  /* Ran out of memory.  */
#define  GLOB_ABORTED   2  /* Read error.  */
#define  GLOB_NOMATCH   3  /* No matches found.  */
#define  GLOB_NOSYS       4   /* Not implemented.  */

... but no "-1" that's why I'm so confused.... I understand it failed, but there's no indication as to why...

Try checking errno...

yeah, I looked through it... if the error returned is not from one of those specified, it's from one of the underlying opendir/readdir/closedir calls... makes sense...
