This example is a terminal handler in C sys level programming, it uses ioctl() subroutine.
Code:
#include &ltstdio.h>
#include &ltsgtty.h>
/* for Solaris Compilation */
#include &ltsys/termios.h>

struct ltchars old, new;
main()
{
  fprintf(stdout, "ORIGINAL TERMINAL ATTRIBUTES:-\n");
  system("stty all");
 
  ioctl(0,TIOCGLTC,&old); ioctl(0,TIOCGLTC,&new);       
  new.t_suspc='\033'; ioctl(0, TIOCSLTC, &new);        
  fprintf(stdout, "\n\nMODIFIED TERMINAL ATTRIBUTES:-\n");
  system("stty all");
  ioctl(0, TIOCSLTC, &old);
