WMEMCMP(3) Library Functions Manual WMEMCMP(3)

compare wide strings

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

The wmemcmp() function compares the wide string s1 against the wide string s2. Both wide strings are assumed to be len wide characters long.

The wmemcmp() function returns zero if the two wide strings are identical, otherwise the difference between the first two differing wide characters is returned. Zero-length wide strings are always identical.
