/* FUNCTION <<wcscmp>>---compare two wide-character strings ANSI_SYNOPSIS #include <wchar.h> int wcscmp(const wchar_t *<[s1]>, *<[s2]>); TRAD_SYNOPSIS int wcscmp(<[s1]>, <[s2]> const wchar_t *<[s1]>, <[s2]>; DESCRIPTION The <<wcscmp>> function compares the wide-character string pointed to by <[s1]> to the wide-character string pointed to by <[s2]>. The sign of a non-zero return value is determined by the sign of the difference between the values of the first pair of wide-character codes that differ in the objects being compared. RETURNS Upon completion, <<wcscmp>> returns an integer greater than, equal to or less than 0, if the wide-character string pointed to by <[s1]> is greater than, equal to or less than the wide-character string pointed to by <[s2]> respectively. PORTABILITY <<wcscmp>> is ISO/IEC 9899/AMD1:1995 (ISO C). No supporting OS subroutines are required. */ /* $NetBSD$ */ /*- * Copyright (c) 1990, 1993 * The Regents of the University of California.
