NAME
       wcsdup - duplicate a wide-character string

SYNOPSIS
       #include <wchar.h>

       wchar_t *wcsdup(const wchar_t *s);

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

       wcsdup():
	   Since glibc 2.10:

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
       On success, wcsdup() returns a pointer to the new wide-character string.  On error, it returns -1, with errno set to indicate the cause	of
       the error.

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.
