wcsncasecmp - compare two fixed-size wide-character strings, ignoring case
#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)):
- Since glibc 2.10:
_POSIX_C_SOURCE >= 200809L
- Before glibc 2.10:
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 (towupper(3), towlower(3)).
The wcsncasecmp() function returns zero if the wide-character strings at
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.
For an explanation of the terms used in this section, see attributes(7).
