Subject: [PATCH] Fix initialization in test/iodelay.cpp
jack_latency_range_t is
struct _jack_latency_range {
jack_nframes_t min;
jack_nframes_t max;
};
and jack_nframes_t is
typedef uint32_t jack_nframes_t;
so it's unsigned. Initialising it with -1 is invalid (at least in C++14). We cannot use {0, 0}, because latency_cb has
jack_latency_range_t range;
range.min = range.max = 0;
if ((range.min != capture_latency.min) || (range.max !=
capture_latency.max)) {
capture_latency = range;
}
so we must not have {0, 0}, otherwise the condition would never be true.
Using UINT32_MAX should be equivalent to the previous -1.
