Typedef Documentation

typedef struct SceDisplayFrameBuf SceDisplayFrameBuf

Structure used with sceDisplaySetFrameBuf to set/update framebuffer. Original screen resolution is 960x544, but the following resolutions can also be supplied as width and height : 480x272, 640x368, 720x408

Note:

- This structure is returned by sceDisplayGetFrameBuf

Enumeration Type Documentation

anonymous enum

Enumerator:

PSP2_DISPLAY_SETBUF_IMMEDIATE	Buffer change effective immediately
PSP2_DISPLAY_SETBUF_NEXTFRAME	Buffer change effective next frame

Function Documentation

int sceDisplayGetFrameBuf	(	SceDisplayFrameBuf *	pParam,
		int	sync
	)

Get current framebuffer parameters

Parameters:

[out]	pParam	- Pointer to a SceDisplayFrameBuf structure which will receive framebuffer parameters.
[in]	sync	- One of ::DisplaySetBufSync

Returns:

0 on success, < 0 on error.

int sceDisplayGetRefreshRate

(

float *

pFps

)

Get current number of fps for the current screen mode.

Parameters:

[out]

pFps

- Pointer to a float variable to store current number of fps.

Returns:

0 on success, < 0 on error.

Note:

- This function returns a theoretical value, this might not be the exact frame rate.

int sceDisplayGetVcount

(

void

)

Number of vertical blank pulses up to now

int sceDisplayRegisterVblankStartCallback

(

SceUID

uid

)

Register callback to be used at each vertical blank start

Parameters:

[in]

uid

- Callback UID

int sceDisplaySetFrameBuf	(	const SceDisplayFrameBuf *	pParam,
		int	sync
	)

Set/Update framebuffer parameters

Parameters:

[in]	pParam	- Pointer to a SceDisplayFrameBuf structure.
[in]	sync	- One of ::DisplaySetBufSync

Returns:

0 on success, < 0 on error.

Note:

- If NULL is provided as pParam pointer, output is blacked out.

(

SceUID

uid

)

Unregister callback used at each vertical blank start

Parameters:

[in]

uid

- Callback UID

int sceDisplayWaitSetFrameBuf

(

void

)
