Formated output from C

I would like to know if there is any way to create some nice formatted output (like bold text) to the console in C. I have played a little with ncurses before but that creates a new "windows" which is destroyed when the program dies.

Regards.

in linux you use escape codes, youse the termios structure and set: c_oflag |= OPOST for output processing, and then (i believe) you can just write your standard escape sequences to stdout:

Wasn't the site at that url just talking about changing the bash prompt? How would I do if I wanted to use something like printf and get output in bold?

Run this program and see if you can learn anything from it:

Code:

#include <stdio.h>



int main(void)

{

  int i, color, attrs[] = { 0, 1, 5, 7 };



  for(i = 0;i < 4;++i)

  {

    printf("\33[0;37m%d | ", attrs[i]);

    for(color = 30;color < 38;++color)

      printf("\33[%d;%dm%d ", attrs[i], color, color);

    printf("\n");

  }



  printf("\33[0;37m");

  return 0;

}

EDIT: A google search on "ansi escape codes" will give you lots of good information about it.
