12 int explain_strcoll_on_error(const char *s1, const char *s2);

15 The explain_strcoll_or_die function is used to call the strcoll(3) sys‐
16 tem call. On failure an explanation will be printed to stderr, obtained
17 from the explain_strcoll(3) function, and then the process terminates
18 by calling exit(EXIT_FAILURE).
19
20 The explain_strcoll_on_error function is used to call the strcoll(3)
21 system call. On failure an explanation will be printed to stderr,
22 obtained from the explain_strcoll(3) function, but still returns to the
23 caller.
24
25 s1 The s1, exactly as to be passed to the strcoll(3) system call.
26
27 s2 The s2, exactly as to be passed to the strcoll(3) system call.
28
30 The explain_strcoll_or_die function only returns on success, see str‐
31 coll(3) for more information. On failure, prints an explanation and
32 exits, it does not return.
33
34 The explain_strcoll_on_error function always returns the value return
35 by the wrapped strcoll(3) system call.
36
38 The explain_strcoll_or_die function is intended to be used in a fashion
39 similar to the following example:
40 int result = explain_strcoll_or_die(s1, s2);
41
43 strcoll(3)
44 compare two strings using the current locale
45
46 explain_strcoll(3)
47 explain strcoll(3) errors
48
49 exit(2) terminate the calling process
