Use the IXCRECV macro to receive the results of a message that was sent using IXCSEND. Most typically, IXCRECV is used by a client to receive the response messages sent by a server in reply to a request. Less typically, IXCRECV is used by a server to determine whether XCF has sent its reply message to the client. IXCRECV has two modes of operation, blocking and non-blocking. A blocking receive will not return to the caller until the subject message is complete. A message is complete, for example, when all of the expected responses have arrived. A non-blocking receive immediately returns to the caller with an indication of whether the subject message is complete.
