CONFIRMED Verb

A TP uses the 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

RECEIVE-AND-WAIT or RECEIVE-IMMEDIATE reply, it must use CONFIRMED to

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

completes immediately; if the local TP chooses to reject the data, it can issue a SEND-

ERROR verb.

Request Details

REQ-UOW-CODE

This field must contain the value 1003, which identifies the CONFIRMED verb.

Consideration

If a 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.
