Function Documentation

sceUmdActivate()

int sceUmdActivate	(	int	unit,
		const char *	drive )

Activates the UMD drive.

Parameters

unit	- The unit to initialise (probably). Should be set to 1.
drive	- A prefix string for the fs device to mount the UMD on (e.g. "disc0:")

Returns

< 0 on error

Example:

// Wait for disc and mount to filesystem
int i;
i = sceUmdCheckMedium();
if(i == 0)
{
   sceUmdWaitDriveStat(PSP_UMD_PRESENT);
}
sceUmdActivate(1, "disc0:"); // Mount UMD to disc0: file system
sceUmdWaitDriveStat(PSP_UMD_READY);
// Now you can access the UMD using standard sceIo functions

sceUmdCancelWaitDriveStat()

int sceUmdCancelWaitDriveStat

(

void

)

Cancel a sceUmdWait* call.

Returns

< 0 on error

sceUmdCheckMedium()

int sceUmdCheckMedium

(

void

)

Check whether there is a disc in the UMD drive.

Returns

0 if no disc present, anything else indicates a disc is inserted.

sceUmdDeactivate()

int sceUmdDeactivate	(	int	unit,
		const char *	drive )

Deativates the UMD drive.

Parameters

unit	- The unit to initialise (probably). Should be set to 1.
drive	- A prefix string for the fs device to mount the UMD on (e.g. "disc0:")

Returns

< 0 on error

sceUmdGetDiscInfo()

int sceUmdGetDiscInfo

(

pspUmdInfo *

info

)

Get the disc info.

Parameters

info	- A pointer to a pspUmdInfo struct

Returns

< 0 on error

sceUmdGetDriveStat()

int sceUmdGetDriveStat

(

void

)

Get (poll) the current state of the UMD drive.

Returns

< 0 on error, one or more of pspUmdState on success

sceUmdGetErrorStat()

int sceUmdGetErrorStat

(

void

)

Get the error code associated with a failed event.

Returns

< 0 on error, the error code on success

sceUmdRegisterUMDCallBack()

int sceUmdRegisterUMDCallBack

(

int

cbid

)

Register a callback for the UMD drive.

Note

Callback is of type UmdCallback

Parameters

cbid	- A callback ID created from sceKernelCreateCallback

Returns

< 0 on error

Example:

int umd_callback(int unknown, int event)
{
     //do something
}     
int cbid = sceKernelCreateCallback("UMD Callback", umd_callback, NULL);
sceUmdRegisterUMDCallBack(cbid);

sceUmdReplacePermit()

int sceUmdReplacePermit

(

void

)

Permit UMD disc being replaced.

Returns

< 0 on error

sceUmdReplaceProhibit()

int sceUmdReplaceProhibit

(

void

)

Prohibit UMD disc being replaced.

Returns

< 0 on error

sceUmdUnRegisterUMDCallBack()

int sceUmdUnRegisterUMDCallBack

(

int

cbid

)

Un-register a callback for the UMD drive.

Parameters

cbid	- A callback ID created from sceKernelCreateCallback

Returns

< 0 on error

sceUmdWaitDriveStat()

int sceUmdWaitDriveStat

(

int

stat

)

Wait for the UMD drive to reach a certain state.

Parameters

stat	- One or more of pspUmdState

Returns

< 0 on error

sceUmdWaitDriveStatCB()

int sceUmdWaitDriveStatCB	(	int	stat,
		unsigned int	timeout )

Wait for the UMD drive to reach a certain state (plus callback)

Parameters

stat	- One or more of pspUmdState
timeout	- Timeout value in microseconds

Returns

< 0 on error

sceUmdWaitDriveStatWithTimer()

int sceUmdWaitDriveStatWithTimer	(	int	stat,
		unsigned int	timeout )

Wait for the UMD drive to reach a certain state.

Parameters

stat	- One or more of pspUmdState
timeout	- Timeout value in microseconds
