int _strncoll(const char *s1, const char *s2, size_t n); 

int _wcsncoll(const wchar_t *s1, const wchar_t *s2, size_t n); 

int _strnicoll(const char *s1, const char *s2, size_t n); 

int _wcsnicoll(const wchar_t *s1, const wchar_t *s2, size_t n); 

int _mbsncoll(const unsigned char *s1, const unsigned char *s2, size_t n); 

int _mbsnicoll(const unsigned char *s1, const unsigned char *s2, size_t n); 

Description 

_strncoll compares n number of elements from the string pointed to by s1 to the string pointed to by s2, according to the current locale's LC_COLLATE category. 

_strnicoll performs like _strncoll but is not case sensitive.
