Usage

svc_fdset is a global variable that specifies the read descriptor bit set on the service machine. This is of interest only if the service programmer decides to write an asynchronous event processing routine; otherwise svc_run() should be used. Writing asynchronous routines in the MVS™ environment is not simple, because there is no direct relationship between the descriptors used by the socket routines and the event control blocks commonly used by MVS programs for coordinating concurrent activities.
