NAME
wcscoll -- compare wide strings according to current collation LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <wchar.h> int wcscoll(const wchar_t *s1, const wchar_t *s2); DESCRIPTION
The wcscoll() function compares the nul-terminated strings s1 and s2 according to the current locale collation order. In the ``C'' locale, wcscoll() is equivalent to wcscmp(). RETURN VALUES
The wcscoll() function returns an integer greater than, equal to, or less than 0, if s1 is greater than, equal to, or less than s2. No return value is reserved to indicate errors; callers should set errno to 0 before calling wcscoll(). If it is non-zero upon return from wcscoll(), an error has occurred. ERRORS
The wcscoll() function will fail if: [EILSEQ] An invalid wide-character code was specified. [ENOMEM] Cannot allocate enough memory for temporary buffers. SEE ALSO
setlocale(3), strcoll(3), wcscmp(3), wcsxfrm(3) STANDARDS
The wcscoll() function conforms to ISO/IEC 9899:1999 (``ISO C99''). BUGS
The current implementation of wcscoll() function disregards LC_COLLATE locales, and falls back to using the wcscmp() function. BSD

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
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ |ATTRIBUTE TYPE |ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ |Interface Stability |wcscoll() is Standard | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe with exceptions | +-----------------------------+-----------------------------+ The wcscoll() and wscoll() functions can be used safely in multithreaded applications as long as setlocale(3C) is not being called to change the locale.
