459 | a newly inserted card. An instance of that driver will then be | ||
460 | eligible to register as a client of this socket. | ||
461 | |||
462 | Register_client() uses the dev_info_t handle to match the | ||
463 | caller with a socket. The driver must have already been bound | ||
464 | to a socket with bind_device() -- in fact, bind_device() | ||
465 | allocates the client structure that will be used. | ||
