hey everyone!
got another problem here.
how would i use the getchar() in a prompt: Press any key to continue
the way i did it was to define a char variable named ch
and then wrote
if you press enter it exits, but if you type anything else it displays it on the screen and you still have to press enter after.
is there anyway to make the program continue without displaying the result to the screen and so the user can press any key they want?
There's a replacement in bash for getchar or get functions of C and C++?Those functions read the next char avaliable in the input stream.
I've tried something like:
OLD_STTY=`stty -g`
stty cbreak -echo
look=`dd if=/dev/tty bs=1 count=1 2>/dev/null`
stty $OLD_STTY
But it is not working... (3 Replies)
Hi,
I would like to read an input from keyboard using getchar. However, if no input (No Carriage return/new line none whatsoever) is given after say, 5 seconds, I would like to skip the getchar and move on. How do I do this in C. I'm using GNU compiler set.

I wanted to make a simple program that writes chracters in a file but i didnt want to press enter .So i found the getchar which doesnt need enter.If i pass (int) getchar to putc ,in the file it shows a P character.The (int) getchar says it is equal to1734747216 so i do (int) getchar-1734747216...

Hi,
What happens to process state when getchar() is called? I wrote a C code in which I call getchar() somewhere down the road. I forgot about that, I started the process, put it in bg and disowned it using "disown". Now, how do I see where that process has gone/how do kill it?
Thanks,
