6.2 wmemcmp—compare wide characters in memory

Synopsis

     #include <wchar.h>
     int wmemcmp(const wchar_t *s1, const wchar_t *s2, size_t n);
     

Description
The wmemcmp function compares the first n wide characters of the object pointed to by s1 to the first n wide characters of the object pointed to by s2. This function is not affected by locale and all wchar_t values are treated identically. The null wide character and wchar_t values not corresponding to valid characters are not treated specially.

If n is zero, s1 and s2 must be a valid pointers and the function behaves as if the two objects compare equal.

No supporting OS subroutines are required.
