NAME
wcpncpy - copy a fixed-size string of wide characters, returning a
pointer to its end
SYNOPSIS
#define _GNU_SOURCE
#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(3) function. It copies at most n wide characters from the
wide-character string pointed to by src, including 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 written, that
is, dest + n - 1.
CONFORMING TO
This function is a GNU extension.
