wcpncpy - copy a fixed-size string of wide characters,
returning a pointer to its end
SYNOPSIS
#include <wchar.h>
wchar_t *wcpncpy (wchar_t *dest, const wchar_t *src, size_t n);
DESCRIPTION
The wcpncpy function is the wide-character equivalent of
the stpncpy function. It copies at most n wide characters
from the wide-character string pointed to by src, includ
ing the terminating L'\0' character, to the array pointed
to by dest. Exactly n wide characters are written at dest.
If the length wcslen(src) is smaller than n, the remaining
wide characters in the array pointed to by dest are filled
with L'\0' characters. If the length wcslen(src) is
greater or equal to n, the string pointed to by dest will
not be L'\0' terminated.
The strings may not overlap.
The programmer must ensure that there is room for at least
n wide characters at dest.
RETURN VALUE
wcpncpy returns a pointer to the last wide character writ
ten, i.e. dest + n - 1.
