Send State

In Send state, a TP controls the conversation. A TP in Send state stays in Send state unless it requests to enter another state or the remote TP detects an error and forces the local TP to enter another state.

Table 4-3 “Send State Intrinsics” lists all the intrinsics that can be called from Send state. It also indicates what state the local TP is in after each intrinsic executes successfully. Notice that MCRcvAndWait can place the local side of the conversation in several different states, depending on the type of information it receives from the remote TP.

The MCDeallocate and MCTest intrinsics have certain parameters listed with them, because only calls with those parameters are allowed in Send state. See the descriptions of MCDeallocate and MCTest in Chapter 5 “ Intrinsic Descriptions” for more information.
