APPC Conversation Verbs
MC_CONFIRM and CONFIRM
Note
This verb can be used only in a half-duplex conversation; it is not valid in a full-duplex
conversation.
In response to the [MC_]CONFIRM verb, the partner TP normally issues the [MC_]CONFIRMED verb to confirm
that it has received the data without error. (If the partner TP encounters an error, it issues the [MC_]SEND_ERROR
verb or abnormally deallocates the conversation.)
The TP can issue the [MC_]CONFIRM verb only if the conversation’s synchronization level, established by the
[MC_]ALLOCATE verb, is
AP_CONFIRM_SYNC_LEVEL.
