.Sh DESCRIPTION
The
.Fn cfsetispeed
function sets the input baud rate stored in the
structure pointed to by
.Fa termios_p
to
.Fa speed .
.Pp
The
.Fn cfsetospeed
function sets the output baud rate stored in the
structure pointed to by
.Fa termios_p
to
.Fa speed .
.Pp
There is no effect on the baud rates set in the hardware until a subsequent
successful call to
.Xr tcsetattr 3C
on the same
.Vt termios
structure.
.Sh RETURN VALUES
Upon successful completion,
.Fn cfsetispeed
and
.Fn cfsetospeed
return
.Sy 0 .
Otherwise
.Sy \(mi1
is returned, and
.Va errno
may be set to indicate the error.
.Sh ERRORS
The
.Fn cfsetispeed
and
.Fn cfsetospeed
functions may fail if:
.Bl -tag -width EINVAL
.It Er EINVAL
The
.Fa speed
value is not a valid baud rate.
.It Er EINVAL
The value of
.Fa speed
is outside the range of possible speed values as specified in
.In termios.h .
