Intrinsic

Definition

MCAllocate

Establishes a mapped conversation between TPs.

MCConfirm

Sends a confirmation request to the remote TP and waits for a reply.

MCConfirmed

Sends a confirmation response to a remote TP that has issued a confirmation request.

MCDeallocate

Ends a mapped conversation between TPs.

MCErrMsg

Provides the message corresponding to a given status info value.

MCGetAllocate

Receives the request from a remote TP to start a conversation and then establishes the conversation.

MCGetAttr

Returns information about a mapped conversation.

MCFlush

Flushes the LU's send buffer.

MCPostOnRcpt

Allows the LU to check the contents of the receive buffer for the specified conversation.

MCPrepToRcv

Informs the remote TP that the local TP is now ready to receive data.

MCRcvAndWait

Waits for information to arrive on the mapped conversation and then receives the information. The information can be data, conversation status, or request for confirmation.

MCRcvNoWait

Similar to MCRcvAndWait, this intrinsic receives any information that has arrived on the conversation but will not wait if no data has arrived.

MCReqToSend

Notifies the remote TP that the local TP is requesting to send data.

MCSendData

Sends data to the remote TP.

MCSendError

Informs the remote TP that the local TP has detected an error.
