hi,

i want to write a program that will make it look like i have pressed a key on the keyboard eventhough i havent physically pressed the key on the keyboard.

like the 'on screen keyboards' where when i press a button using mouse, for the system it looks like it has come from the keyboard.

can anyone please help me in this.. like the articles on net that would help in keyboard programming or the C library and functions and data structures that would help me in solving the above problem.

thanking in advance


PS: i want to write the program using C in LINUX

Your question is intresting. I wonder if you could just write the output of the program directly to the stdin stream but im not sure if other programs would get it or how long it would stay in the buffer.

Its possible that its not possible with C but would have to use assembly. In C the stdin stream is kinda just the black box of sorts for the keayboard and other input methods.

I found a program written in C for X11 that acomplishes this. Mabye you can study the source and figure out how its done.
