14 The explain_tmpfile_or_die function is used to call the tmpfile(3) sys‐
15 tem call. On failure an explanation will be printed to stderr, obtained
16 from the explain_tmpfile(3) function, and then the process terminates
17 by calling exit(EXIT_FAILURE).
18
19 The explain_tmpfile_on_error function is used to call the tmpfile(3)
20 system call. On failure an explanation will be printed to stderr,
21 obtained from the explain_tmpfile(3) function, but still returns to the
22 caller.
23
25 The explain_tmpfile_or_die function only returns on success, see tmp‐
26 file(3) for more information. On failure, prints an explanation and
27 exits, it does not return.
28
29 The explain_tmpfile_on_error function always returns the value return
30 by the wrapped tmpfile(3) system call.
31
33 The explain_tmpfile_or_die function is intended to be used in a fashion
34 similar to the following example:
35 FILE *result = explain_tmpfile_or_die();
36
38 tmpfile(3)
39 create a temporary file
40
41 explain_tmpfile(3)
42 explain tmpfile(3) errors
43
44 exit(2) terminate the calling process
