This interface defined a .I termio structure used to store terminal settings, and a range of .BR ioctl (2) operations to get and set terminal attributes. .PP The .B termio interface is now obsolete: POSIX.1-1990 standardized a modified version of this interface, under the name .BR 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 .BR ioctl (2) operations that existed in System V. (This was done because .BR ioctl (2) was unstandardized, and its variadic third argument does not allow argument type checking.) .PP If you're looking for a page called "termio", then you can probably find most of the information that you seek in either .BR termios (3) or .BR ioctl_tty (2). .SH SEE ALSO .BR reset (1), .BR setterm (1), .BR stty (1), .BR ioctl_tty (2), .BR termios (3), .BR tty (4) .SH COLOPHON This page is part of release 5.10 of the Linux .I man-pages project.
