Device Driver Macros

These macros alias functions of the type dev_foo(DEVICE, ...) to dev_foo_DEVICE(...), allowing code to be written either way.

#define dev_read(dev, buf, count)   dev_read_##dev(buf, count)

Reads count bytes from a device and stores the result in the provided buffer.

#define dev_write(dev, buf, count)   dev_write_##dev(buf, count)

Writes count bytes to a device from the provided buffer.

#define dev_mode(dev, mode)   dev_mode_##dev(mode)

Set the mode of a device.

#define dev_ioctl(dev, request, args...)   dev_ioctl_##dev(request, ##args)

A pass-through to send arbitrary commands to a device (meaning is defined by device driver). This macro means that dev_ioctl(DEVICE_NAME, request, ...) is equivalent to dev_ioctl_DEVICE_NAME(request, ...), so either format may be used.

#define dev_open(dev)   dev_open_##dev()

Gain an exclusive lock on a device driver.

#define dev_close(dev)   dev_close_##dev()

Release an exclusive lock on a device driver.

Device Mode Constants

#define DEV_MODE_IDLE   1

Put the device in low power mode, if applicable.

#define DEV_MODE_ON   2

Device IOCTL Constants

These constants can be used as parameters to some dev_ioctl functions, depending on the specific device. For information on what IOCTLS a driver will accept, check the documentation for that driver.

#define DEV_SEEK   1

Seek the underlying device pointer.

#define DEV_FLUSH   2

Flush any buffered data to the device.

#define DEV_LOCK   3

Lock the device.

#define DEV_OK   0

operation succeeded.

#define DEV_UNSUPPORTED   100

operation is not supported.

#define DEV_NOT_REGISTERED   101

device driver not registered (this constant is no longer used)
