Chapter 3 Using Intrinsics

Table of Contents

Chapter 2 “Conversations” introduced the types of conversations in which transaction programs can participate. This chapter explains how LU 6.2 API intrinsics are used to create the conversations described in Chapter 2 “Conversations”

Table 3-1 “Intrinsics Used in Example Conversations” lists the intrinsics that will be discussed in this chapter. The list is a subset of the LU 6.2 API intrinsics. Chapter 5 “ Intrinsic Descriptions” contains a complete description of all of the intrinsics.

Table 3-1 Intrinsics Used in Example Conversations

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.
`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.
`MCSendData`	Sends data to the remote TP.
