If the given socket is of type AF_UNIX, socket_getpeername will return the Unix filesystem path (e.g. /var/run/daemon.sock) in the address parameter. port If given, this will hold the port associated to address. &reftitle.returnvalues; &return.success; socket_getpeername may also return &false; if the socket type is not any of AF_INET, AF_INET6, or AF_UNIX, in which case the last socket error code is not updated. &reftitle.notes; socket_getpeername should not be used with AF_UNIX sockets created with socket_accept. Only sockets created with socket_connect or a primary server socket following a call to socket_bind will return meaningful values. For having socket_getpeername to return a meaningful value, the socket it is applied upon must of course be one for which the concept of "peer" makes sense. &reftitle.seealso; socket_getsockname socket_last_error socket_strerror
