NAME
       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);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       wcpncpy():
	   Since glibc 2.10:
	       _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
	   Before glibc 2.10:
	       _GNU_SOURCE

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, includ-
       ing  the  terminating  null wide (L'\0'), 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  remain-
       ing  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
       POSIX.1-2008.
