Gasync

The gasync (GIMX asynchronous) library is the evolution of the GE (GIMX events) library.
In addition to input devices, gasync also handles the following components:

• serial ports (DIY USB adapter)
• high-resolution timers (delayed or periodic tasks)
• USB devices (authentication sources)
• HID devices (Logitech Wheels, GPP/Cronus/Titan One)

It also provides a waiting interface based on poll on GNU/Linux and MsgWaitForMultipleObject on Windows.

GNU/Linux implementation

gpoll	ginput			gserial	gtimer	gusb	ghid
poll	evdev	jsdev	X.Org Xi2	termios	timerfd	libusb

Notes:

• ghid is not based on hidraw because write() does not support non-blocking mode.
  
• Being based on libusb, ghid claims the HID interface and detaches the kernel driver. guhid is a uhid wrapper to allow connecting the device back with the kernel.

Windows implementation

gpoll	ginput		gserial	gtimer	gusb	ghid
MsgWaitForMultipleObject	Raw Input	libSDL	COM ports	Waitable Timers	libusb	HID API

Notes:

• The libSDL events are processed synchronously.

Porting to Darwin / MAC OS X

gpoll	ginput	gserial	gtimer	gusb	ghid
poll	libSDL	termios	TODO	libusb

Notes:

• gtimer has to provide a file descriptor to be given to gpoll.
• ginput has to provide a way to capture the inputs (like constraining the mouse cursor into a window).
• Native input events could be added alongside the libSDL events.
