NAME

6       tcgetattr - get the parameters associated with the terminal
7

SYNOPSIS

9       #include <termios.h>
10
11       int tcgetattr(int fildes, struct termios *termios_p);

DESCRIPTION

15       The tcgetattr() function gets the parameters associated with the termi‐
16       nal referred to by fildes and stores them in the termios structure (see
17       termio(7I))  referenced  by  termios_p.  The fildes argument is an open
18       file descriptor associated with a terminal.
19
20
21       The termios_p argument is a pointer to a termios structure.
22
23
24       The tcgetattr() operation is allowed from any process.
25
26
27       If the terminal device supports different input and output baud  rates,
28       the  baud rates stored in the termios structure returned by tcgetattr()
29       reflect the actual baud rates, even if they  are  equal.  If  differing
30       baud rates are not supported, the rate returned as the output baud rate
31       is the actual baud rate. If the terminal device does not support  split
32       baud rates, the input baud rate stored in the termios structure will be
33       0.
34

RETURN VALUES

36       Upon successful completion, 0 is returned. Otherwise,  −1  is  returned
37       and errno is set to indicate the error.
38

ERRORS

40       The tcgetattr() function will fail if:
41
42       EBADF     The fildes argument is not a valid file descriptor.
43
44
45       ENOTTY    The file associated with fildes is not a terminal.
