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 cause of the
- Insufficient memory available to allocate duplicate string.
