The CICS_EpiPurgeTerminal function purges a previously added terminal resource.
The application does not consider the deletion complete until it receives the corresponding CICS_EPI_EVENT_END_TERM event.
The CICS_EpiPurgeTerminal call differs from the CICS_EpiDelTerminal call in that the application does not have to wait until the current transaction finishes or process all outstanding events before issuing the call.
If the terminal resource was autoinstalled, its definition is deleted from the server.
This purge function does not cancel ATI requests already received by the server, and queued against the terminal.
The EPI uses this parameter only for input.
