typedef int SceSysTimerId

Function Documentation

sceSTimerAlloc()

SceSysTimerId sceSTimerAlloc

(

void

)

Allocate a new SysTimer timer instance.

Returns

SysTimerId on success, < 0 on error

sceSTimerFree()

void sceSTimerFree

(

SceSysTimerId

timer

)

Free an instance of a SysTimer timer.

Parameters

timer

- The timer id.

sceSTimerGetCount()

void sceSTimerGetCount	(	SceSysTimerId	timer,
		int *	count )

Get the current SysTimer timer count.

Parameters

timer	- The timer id.
count	- The pointer to an integer into which the count will be written.

sceSTimerResetCount()

void sceSTimerResetCount

(

SceSysTimerId

timer

)

Reset the current SysTimer timer count.

Parameters

timer

- The timer id.

sceSTimerSetHandler()

void sceSTimerSetHandler	(	SceSysTimerId	timer,
		int	cycle,
		int(*	handler )(void),
		int	unk1 )

Setup a SysTimer handler.

Parameters

timer	- The timer id.
cycle	- The timer cycle in microseconds (???). Maximum: 4194303 which represents ~1/10 seconds.
handler	- The handler function. Has to return -1.
unk1	- Unknown. Pass 0.

sceSTimerSetPrscl()

void sceSTimerSetPrscl	(	SceSysTimerId	timer,
		int	unk1,
		int	unk2 )

Set the prescale of a hardware timer.

It can be only set on timers which are in the "not in use" state.

The input signal is divided into the resulting ratio. The ratio has to be less than 1/11.

Parameters

timer	The ID of the timer to set the prescale.
numerator	The numerator of the prescale. Must not be 0.
denominator	The denominator of the prescale. Must not be 0.

Returns

0 on success.

sceSTimerSetTMCY()

void sceSTimerSetTMCY	(	SceSysTimerId	timer,
		int	unk1 )

Unknown purpose.

Probably something to set the cycle of an active timer.

Parameters

timer	The ID of the timer.
unk1	Unknown. Should not be less than 0 and greater 4194304.

Returns

0 on success.

sceSTimerStartCount()

void sceSTimerStartCount

(

SceSysTimerId

timer

)

Start the SysTimer timer count.

Parameters

timer

- The timer id.

sceSTimerStopCount()

void sceSTimerStopCount

(

SceSysTimerId

timer

)

Stop the current SysTimer timer count.

Parameters

timer

- The timer id.
