    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>.

    The following sections are informative.  

    EXAMPLES

    None.  

    APPLICATION USAGE

    None.  

    RATIONALE

    Refer to cfgetispeed() .  

    FUTURE DIRECTIONS

    None.
