DESCRIPTION

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.
