[Bug libc/4588] New: behavior of __path_search / tempnam() with regard to writable TMPDIR

[schizo at debian dot org]

The comment in stdio-common/tempnam.c says that tempnam() validates the
writability of TMPDIR.  In realiy, __path_search just checks to see if the
directory exists.  Should the behavior actually conform to the comment, or
vice-versa?

/* Generate a unique temporary filename using up to five characters of PFX
   if it is not NULL.  The directory to put this file in is searched for
   as follows: First the environment variable "TMPDIR" is checked.
   If it contains the name of a writable directory, that directory is used.
   If not and if DIR is not NULL, that value is checked.  If that fails,
   P_tmpdir is tried and finally "/tmp".  The storage for the filename
   is allocated by `malloc'.  */
