SYNOPSIS

10       #include <libexplain/tempnam.h>
11       char *explain_tempnam_or_die(const char *dir, const char *prefix);
12       char *explain_tempnam_on_error(const char *dir, const char *prefix);
13

DESCRIPTION

15       The explain_tempnam_or_die function is used to call the tempnam(3) sys‐
16       tem call. On failure an explanation will be printed to stderr, obtained
17       from the explain_tempnam(3) function, and then the  process  terminates
18       by calling exit(EXIT_FAILURE).
19
20       The  explain_tempnam_on_error  function  is used to call the tempnam(3)
21       system call. On failure an  explanation  will  be  printed  to  stderr,
22       obtained from the explain_tempnam(3) function, but still returns to the
23       caller.
24
25       dir     The dir, exactly as to be passed to the tempnam(3) system call.
26
27       prefix  The prefix, exactly as to be passed to  the  tempnam(3)  system
28               call.
29

RETURN VALUE

31       The  explain_tempnam_or_die function only returns on success, see temp‐
32       nam(3) for more information. On  failure,  prints  an  explanation  and
33       exits, it does not return.
34
35       The  explain_tempnam_on_error  function always returns the value return
36       by the wrapped tempnam(3) system call.
