Linux 2.6 - man page for wcpcpy (linux section 3)

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

NAME
       wcpcpy - copy a wide-character string, returning a pointer to its end

SYNOPSIS
       #include <wchar.h>

       wchar_t *wcpcpy(wchar_t *dest, const wchar_t *src);

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

       wcpcpy():
	   Since glibc 2.10:
	       _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L

DESCRIPTION
       The  wcpcpy()  function	is  the  wide-character equivalent of the stpcpy(3) function.  It
       copies the wide-character string pointed to by src, including 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 wcslen(src)+1 wide characters
       at dest.

RETURN VALUE
       wcpcpy() returns a pointer to the end of  the  wide-character  string  dest,  that  is,	a
       pointer to the terminating null wide character.

ATTRIBUTES
   Multithreading (see pthreads(7))
       The wcpcpy() function is thread-safe.

CONFORMING TO
       POSIX.1-2008.
