Function Documentation

void* usbCreatePrivate

(

DeviceIntPtr

pDevice

)

Create a private structure for use within this file.

References _myPrivate::fd, and _myPrivate::pDevice.

void usbDestroyPrivate

(

void *

priv

)

Destroy a private structure.

void usbInit	(	DevicePtr	pDev,
		usbType	type
	)

Initialized pDev as a usbMouse, usbKeyboard, or usbOther device.

References FATAL1, GETPRIV, O_NONBLOCK, test_bit, test_bits, usbKeyboard, usbMouse, usbOther, and usbPrint().

Referenced by kbdUSBInit(), mouUSBInit(), and othUSBInit().

void usbOff

(

DevicePtr

pDev

)

Turn pDev off (i.e., stop taking input from pDev).

References GETPRIV.

static void usbPrint ( myPrivate *  priv, const char *  filename, const char *  devname, int  fd  )

Referenced by usbInit().

void usbRead	(	DevicePtr	pDev,
		MOTIONPROC	motion,
		ENQUEUEPROC	enqueue,
		int	minButton,
		BLOCK	block
	)

Read an event from the pDev device. If the event is a motion event, enqueue it with the motion function. Otherwise, enqueue the event with the enqueue function. The block type is passed to the functions so that they may block SIGIO handling as appropriate to the caller of this function.

Since USB devices return EV_KEY events for buttons and keys, minButton is used to decide if a Button or Key event should be queued.
