WCSCASECMP(3) BSD Library Functions Manual WCSCASECMP(3)NAMEwcscasecmp, wcsncasecmp -- compare wide-character strings, ignoring caseLIBRARYStandard C Library (libc, -lc)SYNOPSIS#include <wchar.h> int wcscasecmp(const wchar_t *s1, const wchar_t *s2); int wcsncasecmp(const wchar_t *s1, const wchar_t *s2, size_t len);DESCRIPTIONThe wcscasecmp() and wcsncasecmp() functions compare the nul-terminated strings s1 and s2 and return an integer greater than, equal to, or less than 0, according to whether s1 is lexicographically greater than, equal to, or less than s2 after translation of each corresponding character to lower-case. The strings themselves are not modified. The wcsncasecmp() compares at most len characters.SEE ALSOwcscmp(3)HISTORYThe wcscasecmp() and wcsncasecmp() functions first appeared in NetBSD 4.0.NOTESIf len is zero, wcsncasecmp() returns always 0.BSDAugust 26, 2006 BSD
