wcsncasecmp
WCSNCASECMP(3) Linux Programmer's Manual WCSNCASECMP(3)
NAME
wcsncasecmp - compare two fixed-size wide-character strings, ignoring case
SYNOPSIS
#include <wchar.h>
int wcsncasecmp(const wchar_t *s1, const wchar_t *s2, size_t n);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
wcsncasecmp():
Since glibc 2.10:
_XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
Before glibc 2.10:
_GNU_SOURCE
DESCRIPTION
The wcsncasecmp() function is the wide-character equivalent of the strncasecmp(3) function. It compares the wide-character string pointed
to by s1 and the wide-character string pointed to by s2, but at most n wide characters from each string, ignoring case differences (towup-
per(3), towlower(3)).
RETURN VALUE
The wcsncasecmp() function returns zero if the wide-character strings at s1 and s2, truncated to at most length n, are equal except for
case distinctions. It returns a positive integer if truncated s1 is greater than truncated s2, ignoring case. It returns a negative inte-
ger if truncated s1 is smaller than truncated s2, ignoring case.
VERSIONS
The wcsncasecmp() function is provided in glibc since version 2.1.
CONFORMING TO
POSIX.1-2008. This function is not specified in POSIX.1-2001, and is not widely available on other systems.
NOTES
The behavior of wcsncasecmp() depends on the LC_CTYPE category of the current locale.
