The Start Close Intercept function allows the application to intercept close requests generated when a user selects the close option from the emulator session window. This function intercepts the close request and discards it until a Stop Close Intercept (43) function is requested.

After using this function, your application program can use the Query Close Intercept (42) function to determine when a close request has occurred.
