ioctl_tty(2) System Calls Manual ioctl_tty(2)
ioctl_tty - ioctls for terminals and serial lines
Standard C library (libc, -lc)
#include <asm/termbits.h> /* Definition of constants */
#include <sys/ioctl.h>
int ioctl(int fd, int op, ...);
The ioctl(2) call for terminals and serial ports accepts many
possible operation arguments. Most require a third argument, of
varying type, here called argp or arg.
Use of ioctl() makes for nonportable programs. Use the POSIX
interface described in termios(3) whenever possible.
