Typedef Documentation

typedef int(*) UmdCallback(int unknown, int event)

UMD Callback function.

Enumeration Type Documentation

enum UmdDriveStat

Enumeration for UMD stats.

Enumerator:

UMD_WAITFORDISC	Wait for disc to be inserted.
UMD_WAITFORINIT	Wait for the UMD to be initialised so it can be accessed from the mapped drive.

---

Function Documentation

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(0);
 if(i == 0)
 {
    sceUmdWaitDriveStat(UMD_WAITFORDISC);
 }
 sceUmdActivate(1, "disc0:"); // Mount UMD to disc0: file system
 sceUmdWaitDriveStat(UMD_WAITFORINIT);
 // Now you can access the UMD using standard sceIo functions

int sceUmdCheckMedium

(

int

a

)

Check whether there is a disc in the UMD drive.

Parameters:

a

- Unknown function, set to 0

Returns:

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

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
