sceIoDevctl()

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

SceIoDevInfo info;
sceIoDevctl("ux0:", 0x3001, NULL, 0, &info, sizeof(SceIoDevInfo));

Parameters

dev	- String for the device to send the devctl to (e.g. "ux0:")
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

sceIoIoctl()

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

sceIoIoctlAsync()

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
