PROLOG
       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing 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
       structure.  Similarly, errors resulting from attempts to set baud rates not supported by the terminal device need not be detected until the
       tcsetattr() 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>.

       The following sections are informative.

APPLICATION USAGE

RATIONALE
