EPI Initialization and termination

Any application that needs to use EPI must call the CICS_EpiInitialize function to initialize EPI. Until this call is made, no other EPI function is allowed. The CICS_EpiInitialize function takes a parameter indicating the version of the EPI for which the application was coded. This is to ensure that existing applications continue to run without change if the EPI is extended.

Before an EPI application ends, it must call the CICS_EpiTerminate function to terminate EPI cleanly.

If the Client Daemon is restarted while an application is active, the application must reissue CICS_EpiInitialize and reinstall all the terminals. Restarting the Client Daemon while an application is active is not recommended.
