wcsncmp - compare two wide character substrings

Syntax	#include <wchar.h> int wcsncmp(const wchar_t *ws1, const wchar_t *ws2, size_t n);
Description	wcsncmp() compares the wide character strings ws1 and ws2 lexically up to a maximum length of n. For example: wcsncmp("Sie","Siemens",3) returns 0 (equal), because the first three characters of both arguments match one another.
Return val.	Integer value:
	< 0	In the first n characters, ws1 is lexically less than ws2.
	0	In the first n characters, ws1 and ws2 are lexically equal.
	> 0	In the first n characters, ws1 is lexically greater than ws2.
Notes	Wide character strings terminated with a null wide character code (\0) are expected as arguments. The collating sequence is based on the EBCDIC character set. Restriction This version of the C runtime system only supports 1-byte characters as wide character codes. They are of type wchar_t (see stddef.h). (End)
