CFSETISPEED(P)                                                  CFSETISPEED(P)



NAME
       cfsetispeed - set input baud rate

SYNOPSIS
       #include <termios.h>

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


DESCRIPTION
       The  cfsetispeed()  function  shall set the input 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,  cfsetispeed() shall return 0; otherwise, -1 shall be
       returned, and errno may be set to indicate the error.

ERRORS
       The cfsetispeed() 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  speci-
              fied in <termios.h>.
