Function Documentation

VITASDK_BUILD_ASSERT_EQ() [1/2]

VITASDK_BUILD_ASSERT_EQ	(	0x40	,
		SceMsInfo
	)

ksceMsifGetMsInfo()

int ksceMsifGetMsInfo

(

SceMsInfo *

info

)

VITASDK_BUILD_ASSERT_EQ() [2/2]

VITASDK_BUILD_ASSERT_EQ	(	4	,
		SceMsifErrorCode
	)

ksceMsifDisableSlowCardMode()

int ksceMsifDisableSlowCardMode

(

void

)

Disable slow-card mode.

Slow-card mode does not change the MSIF controller clock. It adds minimum completion delays after successful sector reads and writes, including periodic 350 or 400 ms pauses.

Returns

Always 0.

ksceMsifEnableSlowCardMode()

int ksceMsifEnableSlowCardMode

(

void

)

Enable slow-card mode.

Returns

Always 0.

ksceMsifDisableSlowCardMode

ksceMsifGetSlowCardModeState()

SceBool ksceMsifGetSlowCardModeState

(

void

)

Check whether slow-card mode is enabled.

Returns

SCE_TRUE when enabled, or SCE_FALSE when disabled.

ksceMsifReadSector()

int ksceMsifReadSector	(	SceUInt32	sector,
		void *	buffer,
		SceUInt32	sector_count
	)

Read sectors from the Memory Stick medium.

Parameters

[in]	sector	- First logical sector to read.
[out]	buffer	- Destination for sector_count * SCE_MSIF_SECTOR_SIZE bytes. Must be aligned to 4 bytes.
[in]	sector_count	- Number of sectors to read. Must not be 0.

Returns

0 on success, a negative SceMsifErrorCode value, a mapped medium error, or a fast-mutex error.

ksceMsifWriteSector()

int ksceMsifWriteSector	(	SceUInt32	sector,
		const void *	buffer,
		SceUInt32	sector_count
	)

Write sectors to the Memory Stick medium.

Parameters

[in]	sector	- First logical sector to write.
[in]	buffer	- Source containing sector_count * SCE_MSIF_SECTOR_SIZE bytes. Must be aligned to 4 bytes.
[in]	sector_count	- Number of sectors to write. Must not be 0.

Returns

0 on success, a negative SceMsifErrorCode value, a mapped medium error, or a fast-mutex error.
