NAME
wcscpy - copy a wide-character string
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <wchar.h>
wchar_t *wcscpy(wchar_t *restrict dest, const wchar_t *restrict src);
DESCRIPTION
The wcscpy() function is the wide-character equivalent of the strcpy(3)
function. It copies the wide-character string pointed to by src, in-
cluding the terminating null wide character (L'\0'), to the array
pointed to by dest.
The strings may not overlap.
The programmer must ensure that there is room for at least wc-
slen(src)+1 wide characters at dest.
RETURN VALUE
wcscpy() returns dest.
