tcsendbreak
tcsendbreak(3C) Standard C Library Functions tcsendbreak(3C)NAME
tcsendbreak - send a ``break'' for a specific duration
SYNOPSIS
#include <termios.h>
int tcsendbreak(int fildes, int duration);
DESCRIPTION
The fildes argument is an open file descriptor associated with a terminal.
If the terminal is using asynchronous serial data transmission, tcsendbreak() will cause transmission of a continuous stream of zero-valued
bits for a specific duration. If duration is 0, it will cause transmission of zero-valued bits for at least 0.25 seconds, and not more
than 0.5 seconds. If duration is not 0, it behaves in a way similar to tcdrain(3C).
If the terminal is not using asynchronous serial data transmission, it sends data to generate a break condition or returns without taking
any action.
Attempts to use tcsendbreak() from a process which is a member of a background process group on a fildes associated with its controlling
terminal will cause the process group to be sent a SIGTTOU signal. If the calling process is blocking or ignoring SIGTTOU signals, the
process is allowed to perform the operation, and no signal is sent.
RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The tcsendbreak() function will fail if:
EBADF The fildes argument is not a valid file descriptor.
ENOTTY The file associated with fildes is not a terminal.
The tcsendbreak() function may fail if:
EIO The process group of the writing process is orphaned, and the writing process is not ignoring or blocking SIGTTOU.
