WCSCMP(3) Linux Programmer's Manual WCSCMP(3)

wcscmp - compare two wide-character strings

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

The wcscmp() function is the wide-character equivalent of the strcmp(3) function. It compares the wide-character string pointed to by s1 and the wide-character string pointed to by s2.

The wcscmp() function returns zero if the wide-character strings at s1 and s2 are equal. It returns an integer greater than zero if at the first differing position i, the corresponding wide-character s1[i] is greater than s2[i]. It returns an integer less than zero if at the first differing position i, the corresponding wide-character s1[i] is less than s2[i].

For an explanation of the terms used in this section, see attributes(7).
