NAME

6       cfsetispeed - set input baud rate
7

SYNOPSIS

9       #include <termios.h>
10
11       int cfsetispeed(struct termios *termios_p, speed_t speed);
12
13

DESCRIPTION

15       The  cfsetispeed() function shall set the input baud rate stored in the
16       structure pointed to by termios_p to speed.
17
18       There shall be no effect on the baud rates set in the hardware until  a
19       subsequent  successful call to tcsetattr() with the same termios struc‐
20       ture. Similarly, errors resulting from attempts to set baud  rates  not
21       supported  by  the terminal device need not be detected until the tcse‐
22       tattr() function is called.
23

RETURN VALUE

25       Upon successful completion, cfsetispeed() shall return 0; otherwise, -1
26       shall be returned, and errno may be set to indicate the error.
27

ERRORS

29       The cfsetispeed() function may fail if:
30
31       EINVAL The speed value is not a valid baud rate.
32
33       EINVAL The value of speed is outside the range of possible speed values
34              as specified in <termios.h>.
