Pascal Syntax
FUNCTION gslpat_ (
VAR indicators: INTEGER
): INTEGER [PUBLIC|;
Description
The gslpat subroutine turns on or off the indicators on
the Lighted Program Function Keyboard.
Parameters
indicators Specifies the state of the LPFK indica-
tors. Each bit of indicators corre-
sponds to an indicator on the LPFK,
with the most significant bit setting
the desired state (1=on, 0=off) for the
indicator for LPFK 0, the next most
significant bit setting the state for
the indicator for LPFK 1, and so on.
The default state for all indicators is
off.
An attempt to set the LPFK indicators may fail for a
variety of reasons, the most likely of which is that the
device is not attached. The nature of the problem can be
determined with a specific ioctl to the virtual terminal.
