View Full Version : Checking the keyboard buffer in Posix C?

I'm programming in C on a Linux box and wondered if there was a way to check if the keyboard had been pressed, like kbhit but the Posix function?

you could try this...I don't think its what you want but its really simple...
if ((cin>>X) > "")
that should work if X is declared as a string...

Anything in normal C, that looks like C++ to me.

sorry, wasn't thinking....
scanf( "%d", &n );
I think thats right...I haven't used C in a while

Surely both of those methods block, i.e wait until the user has actually pressed the keyboard before the program can move on.
What I want is a function like kbhit() (that isn't in POSIX C though), that I can poll regularly, e.g:
updateScreenTime(); //arbitary function
if (kbhit()) break; // need the POSIX function that works just
