Function Documentation

int sceIoAssign	(	const char *	dev1,
		const char *	dev2,
		const char *	dev3,
		int	mode,
		void *	unk1,
		long	unk2
	)

Assigns one IO device to another (I guess)

Parameters:

dev1	- The device name to assign.
dev2	- The block device to assign from.
dev3	- The filesystem device to mape the block device to dev1
mode	- Read/Write mode. One of IoAssignPerms.
unk1	- Unknown, set to NULL.
unk2	- Unknown, set to 0.

Returns:

< 0 on error.

Example: Reassign flash0 in read/write mode.

    sceIoUnassign("flash0");
 sceIoAssign("flash0", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0);

int sceIoDevctl	(	const char *	dev,
		unsigned int	cmd,
		void *	indata,
		int	inlen,
		void *	outdata,
		int	outlen
	)

Send a devctl command to a device.

Example: Sending a simple command to a device (not a real devctl)

 sceIoDevctl("ms0:", 0x200000, indata, 4, NULL, NULL);

Parameters:

dev	- String for the device to send the devctl to (e.g. "ms0:")
cmd	- The command to send to the device
indata	- A data block to send to the device, if NULL sends no data
inlen	- Length of indata, if 0 sends no data
outdata	- A data block to receive the result of a command, if NULL receives no data
outlen	- Length of outdata, if 0 receives no data

Returns:

0 on success, < 0 on error

int sceIoIoctl	(	SceUID	fd,
		unsigned int	cmd,
		void *	indata,
		int	inlen,
		void *	outdata,
		int	outlen
	)

Perform an ioctl on a device.

Parameters:

fd	- Opened file descriptor to ioctl to
cmd	- The command to send to the device
indata	- A data block to send to the device, if NULL sends no data
inlen	- Length of indata, if 0 sends no data
outdata	- A data block to receive the result of a command, if NULL receives no data
outlen	- Length of outdata, if 0 receives no data

Returns:

0 on success, < 0 on error

int sceIoIoctlAsync	(	SceUID	fd,
		unsigned int	cmd,
		void *	indata,
		int	inlen,
		void *	outdata,
		int	outlen
	)

Perform an ioctl on a device. (asynchronous)

Parameters:

fd	- Opened file descriptor to ioctl to
cmd	- The command to send to the device
indata	- A data block to send to the device, if NULL sends no data
inlen	- Length of indata, if 0 sends no data
outdata	- A data block to receive the result of a command, if NULL receives no data
outlen	- Length of outdata, if 0 receives no data

Returns:

0 on success, < 0 on error

int sceIoUnassign

(

const char *

dev

)

Unassign an IO device.

Parameters:

dev	- The device to unassign.

Returns:

< 0 on error

Example: See ::sceIoAssign
