termio - System V terminal driver interface

termio is the name of the old System V terminal driver interface. This interface defined a termio structure used to store terminal settings, 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) operations that existed in System V. (This was done because *ioctl*(2) was unstandardized, and its variadic third argument does not allow argument 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).
