C Q

[Kintaro]

I have a question for C/C++

Whats a damn function that can be used like a variable for key input

For example in basic there is the INKEY$ variable which always is the current key being used... Whats the C/C++ equiv?

Try this damn function:

Code: [Select]

[Kintaro]

Oh sorry i ment C++

and it does work.

[Kintaro]

Yes but i want it to do other things until a key is pressed in the loop, then it will interupt it.

[choasforages]

errr, now your making me think. what kind of things and for your previose example
try tacking this on the includes section

Code: [Select]

[Kintaro]

Still wont work

wheres god/voidmain when you need him

[choasforages]

hahah, see if this solves your problem, but you still have to hit enter. im working on it

Code: [Select]

just rember to tell g++
-lpthreads

im looking into unbuffered streams

[Kintaro]

it seems to have given me this

type g++ instead of gcc
it goes like this

g++ -o  blah blah.cpp -lpthreads

[choasforages]

hehehe, got it to work but its probably not that portable, and i used a little bit of help with the usage of ioctl's. if you were to use only ncurses, it would probably end up being better ill try it later but here is that exakmple that works.

compile it with
g++ -o blah blah.cpp -lpthreads

Code: [Select]

[Kintaro]

Its still not working    

Heres the error output:
