Detailed Description

Input queue implementation.

Typedef Documentation

inputq_node_t

typedef struct inputq_node_t inputq_node_t

A list of input queue entries.

Enumeration Type Documentation

anonymous enum

anonymous enum

The input queue system state.

Enumerator
INPUTQ_STATE_INIT	The input queue has not been initialised.
INPUTQ_STATE_RUNNING	The input queue is running.
INPUTQ_STATE_QUIT	The input queue is quitting.

Function Documentation

inputq_end()

void inputq_end

(

void

)

Deregister the Skinkit SDK input queue from RDR, and remove all entries. The input queue must be finalised before the RDR and event systems are terminated.

inputq_start()

HqBool inputq_start

(

void

)

Initialise the Skinkit SDK input queue, and register its implementation in RDR. The RDR and event systems must have been initialised before the input queue is initialised.

Variable Documentation

input_queue

inputq_node_t* input_queue = ((void*)0)

static

The actual input queue.

inputq_nudge_id

int32 inputq_nudge_id = 0

static

An incrementing counter used to break waiting threads out of their loops. inputq_wait() will return TRUE if it is woken up and the nudge ID has changed since the wait started.

inputq_paused

uint32 inputq_paused = 0

static

Count of whether the input queue is paused/resumed using the SWEVT_INPUTS_ENABLE event.

inputq_sources

int32 inputq_sources = 0

static

The number of persistent input sources that might add jobs to the input queue.

enum { ... } inputq_state

The input queue system state.
