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 fail‐ ure an explanation will be printed to stderr, obtained from the explain_tmpfile(3) func‐ tion, 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 tmp‐ file(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();
