Using CEA TSO/E address space services

To use CEA TSO/E address space services, you issue CALLs from high-level language programs that invoke the CEATsoRequest API. The API is a 64-bit C-language based interface that the CEA TSO/E address space manager uses to receive requests from callers and to determine what action to take to process the request.

The CEATsoRequest API supports the following request types:

CeaTsoStart. Start a TSO/E address space.
CeaTsoAttn. Send an attention interrupt to a TSO/E address space started by CEA.
CeaTsoEnd. End a TSO/E address space started by CEA.
CeaTsoPing. Ping a TSO/E address space that was started by CEA to prevent the address space from ending because it has been idle too long.
CeaTsoQuery. Obtain information about a specific TSO/E address space started by CEA.
CeaTsoQueryApp. Obtain information about all the TSO/E address spaces that CEA started for an application.
