This program was inspired by pocket computers. I thought, hey I have this tablet, but I can't use a monitor or a printer. The result was this api! It uses two programs, the api and a "slave" program.
The slave program is meant to be run on a normal computer with a wireless modem attached. It can be called with the api, and will also generate a spoof event. This means the program will generate events that happened to the slave on the master program. WARNING: This has not been tested with other programs that overwrite os.pullEventRaw! It takes 3 command line arguments:
The api is meant to be run on a (wireless) pocket computer, but it will also run just fine on a computer (if they wireless modem is placed on the back). It contains just two functions:
Note that if you want, you can wrap a peripheral on multiple slaves. For instance, you could have a computer for your door and a computer for your monitor, and be handling both with a third computer, or a (wireless) pocket computer.

Note: if you attempt to catch a peripheral event such as monitor_touch, the program will never return a value. If anyone knows how I could fix this, I would appreciate the help. Instead, use something similar to this code:
