I want some random characters to be printed to console and then deleted by "b"
. After this I want to put my own variable so it will be looking like “randomizing”. The problem is that it is happening too fast. I wanted to delay the output by using usleep
or sleep
function but when I’m using it, nothing is printed into console.
Short example:
#include <iostream> #include <unistd.h> using namespace std; int main() { char chars[]={'a','b','c','g','h','u','p','e','y'}; for(int i=0; i<8; i++) { cout << chars[i]; usleep(200000); cout << "b"; } }

Try my little program slowtty from github.
It allows you to simulate in a pty the behaviour of an old rs232c line, by delaying the output per character as stty(1)
command allows to set the baudrate.
You call it with
$ slowtty $ stty 1200 $
and the terminal begins to write characters at a slow pace (like a 1200baud line)
