WCSNCMP(3) Linux Programmer's Manual WCSNCMP(3)NAMEwcsncmp - compare two fixed-size wide-character strings
SYNOPSIS
#include <wchar.h>
int wcsncmp(const wchar_t *s1, const wchar_t *s2, size_t n);
DESCRIPTION
The wcsncmp() function is the wide-character equivalent of the
strncmp() function. It compares the wide-character string pointed to by
s1 and the wide-character string pointed to by s2, but at most n wide
characters from each string. In each string, the comparison extends
only up to the first occurrence of a L'\0' character, if any.
RETURN VALUE
The wcsncmp() function returns zero if the wide-character strings at s1
and s2, truncated to at most length n, are equal. It returns an inte‐
ger greater than zero if at the first differing position i (i < n), 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 (i < n),
the corresponding wide-character s1[i] is less than s2[i].
