HP-UX SNAplus2 R7 APPC Programmer's Guide

Concepts

Receiving Data Asynchronously

• [MC_]DEALLOCATE with a deallocate type of AP_ABEND, AP_ABEND_PROG, AP_ABEND_SVC,or

AP_ABEND_TIMER

• [MC_]GET_ATTRIBUTES

• [MC_]RECEIVE_EXPEDITED_DATA

• [MC_]REQUEST_TO_SEND

• [MC_]SEND_ERROR

• [MC_]SEND_EXPEDITED_DATA

• [MC_]TEST_RTS

• TP_ENDED

If the application issues [MC_]RECEIVE_AND_WAIT (or any other APPC verb) using the asynchronous entry

point, it must not issue any other APPC verbs on this conversation until the callback routine has been called.

In Table 1–6,

Receiving Data Asynchronously, the invoked TP receives data asynchronously.
