• IXJCTL_RATE

    ioctl(ixj, IXJCTL_RATE, iPollrate)

    Return Value

    Returns the new rate if set, -1 if the rate was not accepted.

    Parameters

    The driver poll rate. This value may not be larger than the Kernel clock interrupt rate, as described above. This function requires root permissions on the machine in order to run. The default value is 100. This means the driver will poll all the ixj cards in the system 100 times per second.

    Remarks

    Allows selection of the actual poll rate of the kernel mode driver. This allows finer control over the latency of the DSP and audio packets, and permits adjustment of the polling schedule in case the kernel has been compiled with a higher clock interrupt rate.
