Disabling Abort Processing

To disable abort processing, install a null function pointer (NULLFP) as the abort function by making the following call:

se_abortfp((ISVRP) NULLFP);

If you install a null function as the abort function, no action is taken when an abort key is pressed. Under PCDOS and OS/2, ki(), ki_chk() and evnt_get() will return a 257 for the value of the key pressed. Under VMS, ki(), ki_chk() and evnt_get() will return a keycode value of 257 when either Ctrl-C or Ctrl-Y is read. Under UNIX, no value is returned on receipt of an INTR signal.
