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();
