SYNOPSIS
       #define _GNU_SOURCE
       #include <wchar.h>

       wchar_t *wcsdup(const wchar_t *s);

DESCRIPTION
       the wcsdup() function is the wide-character equivalent of the strdup(3)
       function.  It allocates and returns a new wide-character  string  whose
       initial contents is a duplicate of the wide-character string pointed to
       by s.

       memory for the new wide-character string is  obtained  with  malloc(3),
       and should be freed with free(3).

RETURN VALUE
       The  wcsdup()  function  returns  a  pointer  to the new wide-character
       string, or NULL if sufficient memory was not available.

ERRORS
       ENOMEM Insufficient memory available to allocate duplicate string.

CONFORMING TO
       POSIX.1-2008.  This function is not specified in POSIX.1-2001,  and  is
       not widely available on other systems.
