.TH cfsetispeed 3C "24 Jul 2002" "SunOS 5.11" "Standard C Library Functions"
.SH NAME
cfsetispeed, cfsetospeed \- set input and output baud rate
.SH SYNOPSIS
.LP
.nf
#include <termios.h>

\fBint\fR \fBcfsetispeed\fR(\fBstruct termios *\fR\fItermios_p\fR, \fBspeed_t\fR \fIspeed\fR);
.fi

.LP
.nf
\fBint\fR \fBcfsetospeed\fR(\fBstruct termios *\fR\fItermios_p\fR, \fBspeed_t\fR \fIspeed\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBcfsetispeed()\fR function sets the input baud rate stored in the structure pointed to by \fItermios_p\fR to \fIspeed.\fR
.sp
.LP
The \fBcfsetospeed()\fR function sets the output baud rate stored in the structure pointed to by \fItermios_p\fR to \fIspeed.\fR
.sp
.LP
There is no effect on the baud rates set in the hardware until a subsequent successful call to \fBtcsetattr\fR(3C) on the same \fBtermios\fR structure.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBcfsetispeed()\fR and \fBcfsetospeed()\fR return \fB0\fR. Otherwise \fB\(mi1\fR is returned, and \fBerrno\fR may be set to indicate the error.
.SH ERRORS
.sp
.LP
The \fBcfsetispeed()\fR and \fBcfsetospeed()\fR functions may fail if:
.sp
.ne 2
.mk
.na
\fB\fBEINVAL\fR\fR
.ad
.RS 10n
.rt  
The \fIspeed\fR value is not a valid baud rate.
.RE

.sp
.ne 2
.mk
.na
\fB\fBEINVAL\fR\fR
.ad
.RS 10n
.rt  
The value of \fIspeed\fR is outside the range of possible speed values as specified in \fB<termios.h>\fR\&.
