wcsncasecmp - compare two fixed-size wide-character strings, ignoring case
int wcsncasecmp(const wchar_t *s1, const wchar_t *s2, size_t n);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
|Since glibc 2.10:|
|_POSIX_C_SOURCE >= 200809L|
|Before glibc 2.10:|
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 integer if truncated s1 is smaller than truncated s2, ignoring case.
The wcsncasecmp() function is provided in glibc since version 2.1.

POSIX.1-2008. This function is not specified in POSIX.1-2001, and is not widely available on other systems.
The behavior of wcsncasecmp() depends on the LC_CTYPE category of the current locale.
