MC-CONFIRMED Verb

A TP uses the MC-CONFIRMED verb request to acknowledge receipt of data or

completion of a function.

When the local TP receives a CONFIRM indication in the WHAT-RECEIVED field of a

MC-RECEIVE-AND-WAIT or MC-RECEIVE-IMMEDIATE reply, it must use MC-

CONFIRMED to acknowledge that the data has been received or processed correctly.

MC-CONFIRMED completes immediately; if the local TP chooses to reject the data, it

can issue a MC-SEND-ERROR verb.

The format for MC-CONFIRMED request is:

The MC-CONFIRMED verb has no parameters for either the request or the reply, only

the request header and reply header, which are of the standard SNAX/APC format.

MC-CONFIRMED is supported in the same manner as the standard CONFIRMED verb.

Consideration

If an MC-CONFIRMED verb is processing when SNAX/APC receives a CANCEL

system message from the application program, SNAX/APC deactivates the session and

replies to the cancelled IPC. SNAX/APC frees the internal resources after finishing the

processing of the verb.
