In order to use NIS, the client process must be bound to an NIS server that serves the appropriate domain. That is, the client must be associated with a specific NIS server that services the client's requests for NIS information. Each NIS binding allocates, or uses up, one client process socket descriptor, and each bound domain uses one socket descriptor. Multiple requests to the same domain use the same descriptor. RPCs to the server fail.
Parameters indomain Points to the name of the domain for which to attempt the bind.
