wcscoll(3C) Standard C Library Functions wcscoll(3C) NAME
wcscoll, wscoll - wide character string comparison using collating information SYNOPSIS
#include <wchar.h> int wcscoll(const wchar_t *ws1, const wchar_t *ws2); int wscoll(const wchar_t *ws1, const wchar_t *ws2); DESCRIPTION
The wcscoll() and wscoll() functions compare the wide character string pointed to by ws1 to the wide character string pointed to by ws2, both interpreted as appropriate to the LC_COLLATE category of the current locale. The wcscoll() and wscoll() functions do not change the setting of errno if successful. An application wanting to check for error situations should set errno to 0 before calling wcscoll() or wscoll(). If errno is non-zero on return, an error has occurred. RETURN VALUES
Upon successful completion, wcscoll() and wscoll() return an integer greater than, equal to, or less than 0, depending upon whether the wide character string pointed to by ws1 is greater than, equal to, or less than the wide character string pointed to by ws2, when both are interpreted as appropriate to the current locale. On error, wcscoll() and wscoll() may set errno, but no return value is reserved to indi- cate an error. ERRORS
The wcscoll() and wscoll() functions may fail if: EINVAL The ws1 or ws2 arguments contain wide character codes outside the domain of the collating sequence. USAGE
The wcsxfrm(3C) and wcscmp(3C) functions should be used for sorting large lists. ATTRIBUTES
