wcsncmp - Compare two wide character substrings

Definition	#include <wchar.h> int wcsncmp(const wchar_t *ws1, const wchar_t *ws2, size_t n); wcsncmp compares the wide character strings ws1 and ws2 lexically up to a maximum length of n. For example: Characters that follow the null wide character code are not included in the comparison.
Return val.	< 0 = 0 > 0	In the first n characters, ws1 is lexically less than ws2. In the first n characters, ws1 and ws2 are lexically equal. In the first n characters, ws1 is lexically greater than ws2.
Notes	This version of the C runtime system only supports one-byte characters as wide character codes. Wide character strings terminated with the null wide character (\0) are expected as arguments.
