CFSETISPEED(3P)            POSIX Programmer's Manual           CFSETISPEED(3P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       cfsetispeed - set input baud rate
SYNOPSIS
       #include <termios.h>
       int cfsetispeed(struct termios *termios_p, speed_t speed);

DESCRIPTION
       The cfsetispeed() function shall set the input baud rate stored in  the
       structure pointed to by termios_p to speed.
       There  shall be no effect on the baud rates set in the hardware until a
       subsequent successful call to tcsetattr() with the same termios  struc-
       ture.  Similarly,  errors resulting from attempts to set baud rates not
       supported by the terminal device need not be detected until  the  tcse-
       tattr() function is called.
RETURN VALUE
       Upon successful completion, cfsetispeed() shall return 0; otherwise, -1
       shall be returned, and errno may be set to indicate the error.
ERRORS
       The cfsetispeed() function may fail if:
       EINVAL The speed value is not a valid baud rate.
       EINVAL The value of speed is outside the range of possible speed values
              as specified in <termios.h>.
