I need Help with function in C
Author
What function do I have to use to read from the keyboard, whithout stopping the program?
The program was made in C, DOS.
for example, if I use "scanf" the function waits for the user to press a key. I Need one function don't do this.
(I'm sorry my english is terrible)
If you just want to see if a key is being pressed, use kbhit().
while(!khbit()){//Do stuff here...}
The function is kbhit(), you need the conio.h header.
A example program:
ps: I'm brazilian too. do you know www.pdj.com.br or www.unidev.com.br?
A example program:
#include<conio.h>for(;;) { if(kbhit()) break; puts("bla bla");....}ps: I'm brazilian too. do you know www.pdj.com.br or www.unidev.com.br?
Uh, if ur writing it in a console window then use:
getch(); this is non-blocking, its what u want
getchar(); this is blocking, not what u want.
hope this helps

I don't believe either of these is in any C or C++ standard. I will not swear to it, but I seem to recall what when last I used them, both were blocking though getchar(), unlike getch(), waited for the user to hit Enter.
Basically all IO is blocking; if there's no data available, then it has to wait for some to arrive.
getch() is not *line-buffered*.
