Standard C Library Functions                                   cfsetispeed(3C)



NAME
       cfsetispeed, cfsetospeed - set input and output baud rate

SYNOPSIS
       #include <termios.h>

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


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

DESCRIPTION
       The  cfsetispeed()  function  sets  the  input  baud rate stored in the
       structure pointed to by termios_p to speed.


       The cfsetospeed() function sets the output  baud  rate  stored  in  the
       structure pointed to by termios_p to speed.


       There is no effect on the baud rates set in the hardware until a subse‐
       quent successful call to tcsetattr(3C) on the same termios structure.

RETURN VALUES
       Upon successful completion, cfsetispeed() and cfsetospeed()  return  0.
       Otherwise −1 is returned, and errno may be set to indicate the error.

ERRORS
       The cfsetispeed() and cfsetospeed() functions 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>.
