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.
