mapansi.c - converts a string to input events using MapANSI() function.
This example will also take the created input events
and add them to the input stream using the simple
commodities.library function AddIEvents(). Alternately,
you could open the input.device and use the input device
command IND_WRITEEVENT to add events to the input stream.
