NAME

explain_strcoll_or_die - compare strings using current locale and report errors

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

The explain_strcoll_on_error function is used to call the strcoll(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strcoll(3) function, but still returns to the caller.

	s1		The s1, exactly as to be passed to the strcoll(3) system call.
	s2		The s2, exactly as to be passed to the strcoll(3) system call.

RETURN VALUE

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

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

EXAMPLE

The 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);
