These routines are associated with the server side of the RPC mechanism. Some of them are called by the server side dispatch function, while others (such as Fn svc_run ) are called when the server is initiated.
As currently implemented, Fn svc_exit zeroes the svc_fdset global variable. If RPC server activity is to be resumed, services must be reregistered with the RPC library either through one of the rpc_svc_create3 functions, or using Fn xprt_register . The Fn svc_exit function has global scope and ends all RPC server activity.
