The usual way to get and set terminal modes is with the functions described in the section called “Terminal Modes”. 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 errno = ENOSYS with many kernels, including Linux.
The symbols used in this section are declared in sgtty.h.
function>struct sgttyb/function> This structure is an input or output parameter list for gtty and stty.
Line speed for input
Line speed for output
Erase character
Kill character
Various flags
int function>gtty/function> (int filedes, struct sgttyb *attributes) This function gets the attributes of a terminal.
gtty sets *attributes to describe the terminal attributes of the terminal which is open with file descriptor filedes.
int function>stty/function> (int filedes, struct sgttyb * attributes) This function sets the attributes of a terminal.
stty sets the terminal attributes of the terminal which is open with file descriptor filedes to those described by *filedes.
