NAME

       tmpnam - create a name for a temporary file

SYNOPSIS

       #include <stdio.h>

       char *tmpnam(char *s);

DESCRIPTION

       The  tmpnam()  function generates a unique temporary file-
       name using the path prefix P_tmpdir defined in  <stdio.h>.

       an internal static area which holds the filename, which is
       overwritten  by subsequent calls to tmpnam().  If s is not
       NULL, the filename is returned in s.

RETURN VALUE

       The tmpnam() function returns a pointer to the unique tem-
       porary filename, or NULL if a unique name cannot be gener-
       ated.

ERRORS
