SYNOPSIS

#include <libexplain/strcoll.h>

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

DESCRIPTION

The B]explain_strcoll_or_die function is used to call the I]strcoll(3) system call. On failure an explanation will be printed to I]stderr, obtained from the I]explain_strcoll(3) function, and then the process terminates by calling CW]exit(EXIT_FAILURE).

The B]explain_strcoll_on_error function is used to call the I]strcoll(3) system call. On failure an explanation will be printed to I]stderr, obtained from the I]explain_strcoll(3) function, but still returns to the caller.
I]s1 The s1, exactly as to be passed to the I]strcoll(3) system call.
I]s2 The s2, exactly as to be passed to the I]strcoll(3) system call.

RETURN VALUE

The B]explain_strcoll_or_die function only returns on success, see I]strcoll(3) for more information. On failure, prints an explanation and exits, it does not return.

The B]explain_strcoll_on_error function always returns the value return by the wrapped I]strcoll(3) system call.

EXAMPLE

The B]explain_strcoll_or_die function is intended to be used in a fashion similar to the following example:
int result = explain_strcoll_or_die(s1, s2);
