explain_tmpfile_or_die(3)				     Library Functions Manual					 explain_tmpfile_or_die(3)

NAME
       explain_tmpfile_or_die - create a temporary file and report errors

SYNOPSIS
       #include <libexplain/tmpfile.h>
       FILE *explain_tmpfile_or_die(void);
       FILE *explain_tmpfile_on_error(void);

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

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

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

       The explain_tmpfile_on_error function always returns the value return by the wrapped tmpfile(3) system call.

EXAMPLE
       The explain_tmpfile_or_die function is intended to be used in a fashion similar to the following example:
	      FILE *result = explain_tmpfile_or_die();
