sceUmd_040A7090()

s32 sceUmd_040A7090

(

s32

errorState

)

Get corresponding 1.50 error code used by the UMD drivers. On 1.50, a bunch of error codes were
mistakenly returned by the UMD modules.

Parameters

errorState

Get the 1.50 version of this error code.

Returns

The error code used on 1.50.

sceUmdActivate()

s32 sceUmdActivate	(	s32	mode,
		const char *	aliasName
	)

Activate the UMD drive. This includes assigning the file system, the block device (set to "umd0:") and setting the alias name for the file system access.

Parameters

mode	The initial UMD drive power mode. One of SceUmdDevicePowerModes.
aliasName	The alias name for the mounted filesystem device name. Pass SCE_UMD_ALIAS_NAME.

Returns

SCE_ERROR_OK on success, otherwise SCE_ERROR_ERRNO_INVALID_ARGUMENT.

sceUmdDeactivate()

s32 sceUmdDeactivate	(	s32	mode,
		const char *	aliasName
	)

Deactivate the UMD drive.

Parameters

mode	The new UMD drive power mode. One of SceUmdDevicePowerModes.
aliasName	aliasName The alias name for the mounted filesystem device name. Pass SCE_UMD_ALIAS_NAME.

Returns

SCE_ERROR_OK on success, otherwise SCE_ERROR_ERRNO_INVALID_ARGUMENT.

sceUmdGetDiscInfo()

s32 sceUmdGetDiscInfo

(

SceUmdDiscInfo *

pDiscInfo

)

Get the disc information

Parameters

pDiscInfo

Pointer to a SceUmdDiscInfo structure to retrieve the disc information.

Returns

SCE_ERROR_OK on success, otherwise SCE_ERROR_ERRNO_INVALID_ARGUMENT on invalid arguments; SCE_UMD_ERROR_NO_MEDIUM if there is no UMD medium inserted.

sceUmdRegisterUMDCallBack()

s32 sceUmdRegisterUMDCallBack

(

SceUID

callbackId

)

Register a callback that is called when the UMD disc state changes. Only exactly one callback can be registered at any given time.

Parameters

callbackId

The ID of the callback.

Returns

SCE_ERROR_OK on success, otherwise SCE_ERROR_ERRNO_INVALID_ARGUMENT (when the passed ID does not belong to a callback).

sceUmdUnRegisterUMDCallBack()

s32 sceUmdUnRegisterUMDCallBack

(

SceUID

callbackId

)

Unregister a callback that is called when the UMD disc state changes.

Parameters

callbackId

The ID of the callback.

Returns

SCE_ERROR_OK on success, otherwise SCE_ERROR_ERRNO_INVALID_ARGUMENT (when the passed ID does not match the ID of the previously registered callback).

sceUmdCheckMedium()

s32 sceUmdCheckMedium

(

void

)

Verify the existence of an UMD medium.

Returns

0, if no disc is present, a value != 0 indicates disc is present.

sceUmdWaitDriveStat()

s32 sceUmdWaitDriveStat

(

s32

umdState

)

Wait for a UMD drive status event.

Parameters

umdState

The state to wait for until it occurs. One of SceUmdDiscStates.

Returns

SCE_ERROR_OK, otherwise SCE_ERROR_ERRNO_INVALID_ARGUMENT if the given UMD state isn't one of the following: SCE_UMD_MEDIA_OUT, SCE_UMD_MEDIA_IN, SCE_UMD_NOT_READY, SCE_UMD_READY, SCE_UMD_READABLE Other errors indicate a thread synchronization error.

sceUmdWaitDriveStatWithTimer()

s32 sceUmdWaitDriveStatWithTimer	(	u32	umdState,
		u32	timeout
	)

Wait for a UMD drive status event.

Parameters

umdState	The state to wait for until it occurs. One of SceUmdDiscStates.
timeout	Timeout value in microseconds for the wait.

Returns

SCE_ERROR_OK, otherwise SCE_ERROR_ERRNO_INVALID_ARGUMENT if the given UMD state isn't one of the following: SCE_UMD_MEDIA_OUT, SCE_UMD_MEDIA_IN, SCE_UMD_NOT_READY, SCE_UMD_READY, SCE_UMD_READABLE. Other errors indicate a thread synchronization error.

sceUmdWaitDriveStatCB()

s32 sceUmdWaitDriveStatCB	(	u32	umdState,
		u32	timeout
	)

Wait for a UMD drive status event with callback.

Parameters

umdState	The state to wait for until it occurs. One of SceUmdDiscStates.
timeout	Timeout value in microseconds for the wait.

Returns

SCE_ERROR_OK, otherwise SCE_ERROR_ERRNO_INVALID_ARGUMENT if the given UMD state isn't one of the following: SCE_UMD_MEDIA_OUT, SCE_UMD_MEDIA_IN, SCE_UMD_NOT_READY, SCE_UMD_READY, SCE_UMD_READABLE Other errors indicate a thread synchronization error.
