FUNCTION
<<wcscmp>>---compare two wide-character strings
ANSI_SYNOPSIS
#include <wchar.h>
int wcscmp(const wchar_t *<[s1]>, *<[s2]>);
TRAD_SYNOPSIS
int wcscmp(<[s1]>, <[s2]>
const wchar_t *<[s1]>, <[s2]>;
DESCRIPTION
The <<wcscmp>> function compares the wide-character string pointed to
by <[s1]> to the wide-character string pointed to by <[s2]>.
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.
RETURNS
Upon completion, <<wcscmp>> returns an integer greater than, equal to
or less than 0, if the wide-character string pointed to by <[s1]> is
greater than, equal to or less than the wide-character string pointed
to by <[s2]> respectively.
PORTABILITY
<<wcscmp>> is ISO/IEC 9899/AMD1:1995 (ISO C).
No supporting OS subroutines are required.
