wcsdup - duplicate a wide-character string

#include <wchar.h>
wchar_t *wcsdup(const wchar_t *s);

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

    Since glibc 2.10:
        _POSIX_C_SOURCE >= 200809L
    Before glibc 2.10:
        _GNU_SOURCE

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).

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