NAME
wcscasecmp, wcsncasecmp — compare wide-character strings, ignoring case
LIBRARY
Standard 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);
DESCRIPTION
The
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.
HISTORY
The wcscasecmp() and wcsncasecmp() functions first appeared in NetBSD 4.0.
NOTES
If len is zero, wcsncasecmp() returns always 0.
