| |
| <p><a name="index-terminal-modes_002c-BSD-1997"></a> |
| The usual way to get and set terminal modes is with the functions described |
| in <a href="Terminal-Modes.html#Terminal-Modes">Terminal Modes</a>. However, on some systems you can use the |
| BSD-derived functions in this section to do some of the same thing. On |
| many systems, these functions do not exist. Even with the GNU C library, |
| the functions simply fail with <code>errno</code> = <code>ENOSYS</code> with many |
| kernels, including Linux. |
| |
| <p>The symbols used in this section are declared in <samp><span class="file">sgtty.h</span></samp>. |
