Description
The gseven subroutine enables the reporting of events of
a given type. If the device producing the event is
enabled, then gseven lets it put data into the ring
buffer. If the event type is not recognized, no action
is taken.
A valid input ring must be defined during the GSL
initialization.
Parameters
event The recognized events are as follows:
1 Keystroke
3 Locator movement or button
4 Lighted Program Function Key (LPFK)
5 Valuator
After GSL initialization, only the keyboard is enabled.
If the application wishes the other input devices
enabled, it must explicitly enable them with this
command.
Return Value
GS_SUCC Successful.
GS_EVNT Invalid event type.
GS_UNSC Unsuccessful.
