Returned Parameters

Remarks

The DISCONNECT PRESENTATION SPACE function drops the connection between your HLLAPI application program and the host PS. Once the DISCONNECT PRESENTATION SPACE function has been called, functions that interact with the host PS, such as the SEND KEY (3), WAIT (4), and RESERVE (11) functions are no longer valid.

The DISCONNECT PRESENTATION SPACE function does not reset the session parameters to the defaults. Your HLLAPI application must call the RESET SYSTEM (21) function to reset the defaults. Your HLLAPI application should disconnect from all connected host PSs before exiting.
