TERMIOS(3C) Standard C Library Functions TERMIOS(3C)

NAME


termios - general terminal interface

SYNOPSIS


#include <termios.h>

int tcgetattr(int fildes, struct termios *termios_p);


int tcsetattr(int fildes, int optional_actions,
const struct termios *termios_p);


int tcsendbreak(int fildes, int duration);


int tcdrain(int fildes);


int tcflush(int fildes, int queue_selector);


int tcflow(int fildes, int action);


speed_t cfgetospeed(const struct termios *termios_p);


int cfsetospeed(struct termios *termios_p, speed_t speed);


speed_t cfgetispeed(const struct termios *termios_p);


int cfsetispeed(struct termios *termios_p, speed_t speed);


#include <sys/types.h>
#include <termios.h>

pid_t tcgetpgrp(int fildes);


int tcsetpgrp(int fildes, pid_t pgid);


pid_t tcgetsid(int fildes);


DESCRIPTION


These functions describe a general terminal interface for controlling
asynchronous communications ports. A more detailed overview of the
terminal interface can be found in termio(4I), which also describes an
ioctl(2) interface that provides the same functionality. However, the
function interface described by these functions is the preferred user
interface.


Each of these functions is now described on a separate manual page.
