void leventClear

(

LEvent *

le

)

leventInit()

static void leventInit ( LEvent *  le, bool  signaled, bool  autoclear  )

inlinestatic

Initializes a user-mode light event.

Parameters

[out]	le	Pointer to LEvent structure.
[in]	signaled	Whether the event starts off in signaled state.
[in]	autoclear	Autoclear flag.

leventSignal()

void leventSignal

(

LEvent *

le

)

Signals a user-mode light event.

Parameters

[in]

le

Pointer to LEvent structure.

leventTryWait()

bool leventTryWait

(

LEvent *

le

)

Polls a user-mode light event.

Parameters

[in]

le

Pointer to LEvent structure.

Returns

true if event is signaled, false otherwise.

leventWait()

bool leventWait	(	LEvent *	le,
