ioctl_tty(2)               System Calls Manual              ioctl_tty(2)

НАЗВАНИЕ

       ioctl_tty - ioctls for terminals and serial lines

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <asm/termbits.h>  /* Definition of constants */
       #include <sys/ioctl.h>

       int ioctl(int fd, int op, ...);

ОПИСАНИЕ

       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.
