[PD-dev] getting Pd logical time in C

[Hans-Christoph Steiner]

I guess I should really post some example code:

int timestamp;

hid_get_events(x)
{
    // fill an array with the data that I get
}

hid_read(x)
{
     int right_now = get_logical_time();
     if(right_now > timestamp)
	hid_get_events_into_array(x);
     hid_output_events_from_array(x);
}
