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

       cfsetospeed — set output baud rate

SYNOPSIS

       #include <termios.h>

       int cfsetospeed(struct termios *termios_p, speed_t speed);

DESCRIPTION

       The cfsetospeed() function shall set the output 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, cfsetospeed() shall return 0; otherwise, it shall return −1 and errno may  be
       set to indicate the error.

ERRORS

       The cfsetospeed() 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.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       Refer to cfgetispeed().

FUTURE DIRECTIONS

       None.
