NAMEwcsncmp - compare part of two wide-character strings
SYNOPSIS
#include <wchar.h>
int wcsncmp(const wchar_t *ws1, const wchar_t *ws2, size_t n);
DESCRIPTION
The wcsncmp() function shall compare not more than n wide-character
codes (wide-character codes that follow a null wide-character code are
not compared) from the array pointed to by ws1 to the array pointed to
by ws2.
The sign of a non-zero return value shall be determined by the sign of
the difference between the values of the first pair of wide-character
codes that differ in the objects being compared.
RETURN VALUE
Upon successful completion, wcsncmp() shall return an integer greater
than, equal to, or less than 0, if the possibly null-terminated array
pointed to by ws1 is greater than, equal to, or less than the possibly
null-terminated array pointed to by ws2, respectively.
