WCPNCPY(3)						     Linux Programmer's Manual							WCPNCPY(3)

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:
	       _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, including the terminating null wide (L''), to the array pointed to by dest.  Exactly n  wide  charac-
       ters  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'' characters.  If the length wcslen(src) is greater than or equal to n, the string pointed to by dest  will  not  be  L''
       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.
