NAME         top

       termio - System V terminal driver interface

DESCRIPTION         top

       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).
