Описание (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).


Возвращаемое значение (Return value)

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

Ошибки (Error)

ENOMEM Insufficient memory available to allocate duplicate
              string.
