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);                             
}

TERMIO(7)                                                    Linux Programmer's Manual                                                   TERMIO(7)

NAME

       termio - System V terminal driver interface

DESCRIPTION

       termio  is  the  name of the old System V terminal driver interface.  This interface defined a termio structure used to store terminal set-
       tings, and a range of ioctl(2) operations to get and set terminal attributes.

       The termio interface is now obsolete: POSIX.1-1990 standardized a modified version of this interface, under the name termios.  The  POSIX.1
       data  structure differs slightly from the System V version, and POSIX.1 defined a suite of functions to replace the various ioctl(2) opera-
       tions that existed in System V.  (This was done because ioctl(2) was unstandardized, and its variadic third argument does not  allow  argu-
       ment type checking.)

       If  you're  looking  for  a  page called "termio", then you can probably find most of the information that you seek in either termios(3) or
       ioctl_tty(2).
