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 specified in <termios.h>.
