wmemcmp(3)               Library Functions Manualwmemcmp(3)

NAME        top

       wmemcmp - compare two arrays of wide-characters

LIBRARY        top

       Standard C library (libc,-lc)

SYNOPSIS        top

#include <wchar.h>int wmemcmp(size_t n;const wchar_ts1[n], const wchar_ts2[n], size_tn);

DESCRIPTION        top

       Thewmemcmp() function is the wide-character equivalent of thememcmp(3) function.  It compares then wide-characters starting ats1 and then wide-characters starting ats2.

RETURN VALUE        top

       Thewmemcmp() function returns zero if the wide-character arrays       of sizen ats1 ands2 are equal.  It returns an integer greater       than zero if at the first differing positioni (i <n), the       corresponding wide-characters1[i] is greater thans2[i].  It       returns an integer less than zero if at the first differing       positioni (i <n), the corresponding wide-characters1[i] is less       thans2[i].
