wcsncmp — compare part of two wide-character strings

#include <wchar.h>

int wcsncmp(const wchar_t *ws1, const wchar_t *ws2, size_t n);

The wcsncmp() function compares 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 is 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.

Upon successful completion, wcsncmp() returns 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.
