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); 

The wcsncasecmp function is the wide-character equivalent of the strncasecmp 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, towlower).

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.

This function is a GNU extension.

strncasecmp(3), wcsncmp(3)

The behaviour of wcsncasecmp depends on the LC_CTYPE category of the current locale.
