Title: C Q
Post by: Kintaro on 8 November 2002, 15:53

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?

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

type g++ instead of gcc
it goes like this

g++ -o  blah blah.cpp -lpthreads

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]

Heres the error output:

ooops, i feel stupid its

g++ -o blah blah.cpp -lpthread

extra s on the -lpthread was fooking it up

Post by: Kintaro on 13 November 2002, 11:22

Cool it works, but is there a more simple way?

I dont exactly need a thread just a variable that tells me the value of the key being pressed for example:

Code: [Select]

Do you get what i mean?

Post by: smokey on 13 November 2002, 16:13

Code: [Select]

Do you get what i mean?[/qb]<hr></blockquote>

How about this

Code: [Select]

My code isn't the neatest or the greatest and you could probably remove the keypress() function but otherwise it might work. I havent tested it.
