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>.
