pub fn process_start_token(pid: u32) -> Option<String>Expand description
Layer 2’s reading: an opaque, platform-local token for when pid’s process started.
Compared only by string equality against a token read freshly on the same machine. Nothing converts between platform encodings and nothing parses either one, so the two readings below never have to be reconciled.
| Platform | Token |
|---|---|
| Linux | field 22 of /proc/<pid>/stat, clock ticks since boot |
| macOS | proc_bsdinfo.pbi_start_tvsec / pbi_start_tvusec, as seconds.microseconds |
