Get the path (if any) of a socket

final public function getPath(): ?string;


  • null - if the socket does not have a path, for example, if created with socketpair()
  • a - string if the socket does have a path; this is usually - but not always - a filesystem path. For example, Linux supports 'abstract' unix sockets, which have a path beginning with a null byte and do not correspond to the filesystem.
