Ioctl manual

ioctl. POSIX specification: www.doorway.ru LSB specification: www.doorway.ru Mac OS X Manual Page For ioctl (2) IOCTL (2) BSD System Calls Manual IOCTL (2) NAME ioctl -- control device SYNOPSIS #include ioctl.h int ioctl(int fildes, unsigned long request, ); DESCRIPTION The ioctl() function manipulates the underlying device parameters of spe-. cial special. cial files. The ioctl () function manipulates the underlying device parameters of spe- cial files. In particular, many operating characteristics of character special files (e.g. terminals) may be controlled with ioctl () requests. The argument d must be an open file descriptor. An ioctl () request has encoded in it whether the argument is an ``in'', ``out.

Ioctl's are undocumented Linux internals, liable to be changed without warning. (And indeed, this page more or less describes the situation as of kernel version ; there are many minor and not-so-minor differences with earlier versions.). IOCTL_LIST(2) Linux Programmer's Manual IOCTL_LIST(2) NAME top ioctl_list - list of ioctl calls in Linux/i kernel DESCRIPTION top This is Ioctl List , a list of ioctl calls in Linux/i kernel It contains ioctls from. For each ioctl, its numerical value, its name, and its argument type are given. The ioctl(2) call for terminals and serial ports accepts many possible command 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.
