The answer area (ANSAREA) contains information about the message and its responses. Consider the following for specifying an answer area with IXCRECV:
  • The answer area header, which is mapped by ixcysrvr_tAnsArea of the mapping macro IXCYSRVR, summarizes the state of the message and its responses.
  • The answer area contains the following information about the sender, the message, and the response:
    • The "send descriptor" for the sender of the request, which is mapped by ixcysrvr_tSendDescriptor, and provides information about the original message sent on the IXCSEND macro.
    • The "target descriptor" for each requested target, which is mapped by ixcysrvr_tTargetDescriptor, and provides information about an individual target.
    • The "response descriptor"for each requested response, which is mapped by ixcysrvr_tResponseDescriptor, and provides information about an individual response.
    Note that the order of the target/response descriptors does not necessarily correspond to the order of target systems specified in the originating IXCSEND invocation
