Functions ¶
func Read ¶
Read reads the "PID file" at path, and returns the PID if it contains a valid PID of a running process, or 0 otherwise. It returns an error when failing to read the file, or if the file doesn't exist, but malformed content is ignored. Consumers should therefore check if the returned PID is a non-zero value before use.
