PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

13       cfsetispeed — set input baud rate
14

SYNOPSIS

16       #include <termios.h>
17
18       int cfsetispeed(struct termios *termios_p, speed_t speed);
19

DESCRIPTION

21       The cfsetispeed() function shall set the input baud rate stored in  the
22       structure pointed to by termios_p to speed.
23
24       There  shall be no effect on the baud rates set in the hardware until a
25       subsequent successful call to tcsetattr() with the same termios  struc‐
26       ture.  Similarly,  errors resulting from attempts to set baud rates not
27       supported by the terminal device need not be detected until  the  tcse‐
28       tattr() function is called.
29

RETURN VALUE

31       Upon successful completion, cfsetispeed() shall return 0; otherwise, −1
32       shall be returned, and errno may be set to indicate the error.
33

ERRORS

35       The cfsetispeed() function may fail if:
36
37       EINVAL The speed value is not a valid baud rate.
38
39       EINVAL The value of speed is outside the range of possible speed values
40              as specified in <termios.h>.
