I was wondering how to send/receive signals to and fo hardware with c++? I'm not asking for a complete description, just a phrase that I can search google with to get a tutorial on this subject. The subject being, for instance, how to code for one program to tell another program that the 'P' button on the keyboard has been pushed or that the mouse was moved up y and over x, when the keyboad 'P' or mouse was never physically touched. Thanks for your advice in advance.
