CFSETOSPEED(3P)           POSIX Programmer's Manual          CFSETOSPEED(3P)

PROLOG         top

       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         top

       cfsetospeed — set output baud rate

SYNOPSIS         top

       #include <termios.h>

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

DESCRIPTION         top

       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         top

       Upon successful completion, cfsetospeed() shall return 0; otherwise,
       it shall return −1 and errno may be set to indicate the error.

ERRORS         top

       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         top

APPLICATION USAGE         top

RATIONALE         top
