events in c?

[mikledet]

Hi all,

Is there a way, to have a program in C, react to events,
such as a key stroke?
I mean, to have the program be event driven, for example - no matter at what point the execution of the program is, if key is pressed - it should execude func().

Any pointer, example code, book referance or url will be very welcome.

Thanks.

(yes, I am new to c...)

Well,

I guess it has to do with CallBack function usage right?

I understand how to define and write a call back function,
but i dont understand, how can i tell the system to call my call back - when lets say "x" was pressed?

Thanks

Under which OS do you need this ?.
If DOS/Windows then think about the interrupts.
If UNIX then think about Signals

Thanks - however, in the mean while i have read some more, and now I know better what i am looking for.
It looks like what I need is a multithreaded application - in which, one thread will be monitoring keyboard input,in paralel to another thread that will do other stuff.
Any pointers and url's about multithread programing in C (dos/win) will be most welcome.

Thanks.
