NAME

       explain_tempnam_or_die - create a name for a temporary file and report errors

SYNOPSIS

       #include <libexplain/tempnam.h>
       char *explain_tempnam_or_die(const char *dir, const char *prefix);
       char *explain_tempnam_on_error(const char *dir, const char *prefix);

DESCRIPTION

       The explain_tempnam_or_die function is used to call the tempnam(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_tempnam(3) function, and then the process terminates
       by calling exit(EXIT_FAILURE).

       The  explain_tempnam_on_error  function  is  used  to  call  the  tempnam(3)  system  call. On failure an
       explanation will be printed to stderr, obtained from the explain_tempnam(3) function, but  still  returns
       to the caller.

       dir     The dir, exactly as to be passed to the tempnam(3) system call.

       prefix  The prefix, exactly as to be passed to the tempnam(3) system call.

RETURN VALUE

       The  explain_tempnam_or_die  function  only  returns  on success, see tempnam(3) for more information. On
       failure, prints an explanation and exits, it does not return.

       The explain_tempnam_on_error function always returns the value return by the  wrapped  tempnam(3)  system
       call.

EXAMPLE

       The explain_tempnam_or_die function is intended to be used in a fashion similar to the following example:
              char *result = explain_tempnam_or_die(dir, prefix);
