The XCF receive service (IXCRECV macro) is one of the macros that comprise the XCF client/server interfaces. With these interfaces, a "client" can send a request to a "server" for processing and then receive the "results" provided by the server. Related macros include the XCF server interface (IXCSRVR macro) that is used to create servers, and the XCF send service (IXCSEND macro) that is used to send requests to servers and responses to clients. See IXCSRVR — Define a Server to XCF and IXCSEND — Send Client/Server Requests and Responses.

The IXCRECV macro completes a parameter list with caller provided data and calls the XCF service routine. Depending on the request type specified, XCF blocks (suspends) processing until all of the expected responses arrive or returns information about the status of the request.

For guidance information and other details on using IXCRECV with the client/server interfaces, see the IXCRECV topic in the chapter "Using XCF for Client/Server Communication" of z/OS MVS Programming: Sysplex Services Guide.
