7.2.5 Control trigger key’s key event. (FOR PA96x/PA982 Only)

Function Description:

This function is used to inform system if necessary to generate key event for trigger key.

Function call:

void EnableTriggerKeyEvent(BOOL fON)

Parameter(Input)

fON: BOOL: TRUE = Enable key event.

False = Don’t generate key event.

repeated event generation may cause some trouble for AP By passing FALSE to this

function can prevent upcoming event generation.

Return code:

TRUE = trigger is pressed.

Example:

#define kKeybdTriggerEventName TEXT("KeybdTriggerChangeEvent")

#define kKeybdAlphaKeyEventName TEXT("KBDAlphaKeyChangeEvent")

#define LEFT_TRIGGER_KEY 1

#define RIGHT_TRIGGER_KEY 2

gKeyEvents[0] = CreateEvent(NULL, TRUE, FALSE, kKeybdTriggerEventName);

gKeyEvents[1] = CreateEvent(NULL, TRUE, FALSE, kKeybdAlphaKeyEventName);

while (1)

{

WaitForMultipleObjects(2, gKeyEvents, FALSE, INFINITE);

TriggerKeyStatus(LEFT_TRIGGER_KEY);
