Detailed Description¶

Sample-clock state. Treat the fields as read-only from the outside; mutate only through the functions below.

Public Attributes Documentation¶

variable epoch_mono_ns¶

uint64_t dp_sample_clock_t::epoch_mono_ns;

CLOCK_MONOTONIC baseline for pacing.

variable epoch_real_ns¶

uint64_t dp_sample_clock_t::epoch_real_ns;

CLOCK_REALTIME baseline for stamping.

variable fs¶

double dp_sample_clock_t::fs;

sample rate (Hz).

variable has_anchor¶

int dp_sample_clock_t::has_anchor;

nonzero once track() has adopted a real observed (timestamp, n) pair; init()/reset() start at 0 the receive-side counterpart of the TX-side epoch capture, so the first track() call always adopts rather than tolerance-gating against an arbitrary construction-time guess.

variable max_late_ns¶

uint64_t dp_sample_clock_t::max_late_ns;

worst lateness observed (ns).

variable n¶

uint64_t dp_sample_clock_t::n;

cumulative samples advanced.

variable resync¶

int dp_sample_clock_t::resync;

nonzero: pace() re-anchors on underrun.

variable underruns¶

uint64_t dp_sample_clock_t::underruns;

pace() calls that arrived past deadline.
