byteLength :: Integral a => a Source #

The number of bytes in an input event.

Event handling

interpretSpaceNav Source #

Arguments

:: ByteString	The bytes from devinput.
-> SpaceNav	The corresponding SpaceNavigator data.

Interpret SpaceNavigator event bytes on a Linux input deviceThis interpretation is based on <https://github.com/vrpn/vrpn/blob/master/vrpn_3DConnexion.h> and <https://github.com/vrpn/vrpn/blob/master/vrpn_3DConnexion.c>.

readSpaceNav Source #

Arguments

:: FilePath	The SpaceNavigator device, e.g., "/dev/input/spacenav0".
-> IO [SpaceNav]	Action to read the SpaceNavigator data.

Read a stream of SpaceNavigator data.
