/*
FUNCTION
<<wcscat>>---concatenate two wide-character strings
INDEX
wcscat
ANSI_SYNOPSIS
#include <wchar.h>
wchar_t *wcscat(wchar_t *<[s1]>, const wchar_t *<[s2]>);
TRAD_SYNOPSIS
wchar_t *wcscat(<[s1]>, <[s2]>
wchar_t *<[s1]>;
const wchar_t *<[s2]>;
DESCRIPTION
The <<wcscat>> function appends a copy of the wide-character string
pointed to by <[s2]> (including the terminating null wide-character
code) to the end of the wide-character string pointed to by <[s1]>.
The initial wide-character code of <[s2]> overwrites the null
wide-character code at the end of <[s1]>. If copying takes place between
objects that overlap, the behaviour is undefined.
RETURNS
The <<wcscat>> function returns <[s1]>;
no return value is reserved to indicate an error.
PORTABILITY
<<wcscat>> is ISO/IEC 9899/AMD1:1995 (ISO C).
No supporting OS subroutines are required.
