NAME

wcsncmp - 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.
