wcscoll(3C) wcscoll(3C)
NAME
wcscoll - wide character string comparison using collating
information
SYNOPSIS
#include <wchar.h>
int wcscoll(const wchar_t *ws1, const wchar_t *ws2);
DESCRIPTION
wcscoll is part of the X/Open Portability Guide Issue 4
optional Enhanced Internationalization feature group. It
compares the wide character string pointed to by ws1 to the
wide character string pointed to by ws2, which are both
interpreted as appropriate to the LC_COLLATE category of the
current locale.
Return Values
wcscoll returns 0 and sets errno to ENOSYS.
Errors
In the following conditions, wcscoll fails and sets errno to:
EINVAL The ws1 or ws2 arguments contain wide character codes
outside the domain of the collating sequence.
ENOSYS The function is not supported
USAGE
Since no return value is reserved to show an error, if you
want to check for errors, you should set errno to 0, call
wcscoll, and then check errno. If it is non-zero, you can
assume that an error has occurred.
Use wcsxfrm and wcscmp for sorting large lists of wide
character strings.
