+ * This method initializes a Unix domain or "local" server socket. Such
+ * a socket has a name in the filesystem, like an ordinary file. To
+ * connect, a client supplies the socket's filename, and the usual
+ * permission checks on socket apply.
+ *
+ * This makes Unix domain sockets useful for communication between the
+ * programs being run by a specific user on a single machine: the
+ * operating system takes care of authentication, and the user's home
+ * directory or profile directory provide natural per-user rendezvous
+ * points.
+ *
+ * Since Unix domain sockets are always local to the machine, they are
+ * not affected by the nsIIOService's 'offline' flag.
+ *
+ * The system-level socket API may impose restrictions on the length of
+ * the filename that are stricter than those of the underlying
+ * filesystem. If the file name is too long, this returns
+ * NS_ERROR_FILE_NAME_TOO_LONG.
+ *
+ * All components of the path prefix of |aPath| must name directories;
+ * otherwise, this returns NS_ERROR_FILE_NOT_DIRECTORY.
+ *
+ * This call requires execute permission on all directories containing
+ * the one in which the socket is to be created, and write and execute
+ * permission on the directory itself. Otherwise, this returns
+ * NS_ERROR_CONNECTION_REFUSED.
+ *
+ * This call creates the socket's directory entry. There must not be
+ * any existing entry with the given name. If there is, this returns
+ * NS_ERROR_SOCKET_ADDRESS_IN_USE.
+ *
+ * On systems that don't support Unix domain sockets at all, this
+ * returns NS_ERROR_SOCKET_ADDRESS_NOT_SUPPORTED.
+ *
+ * @param aPath nsIFile
+ * The file name at which the socket should be created.
+ *
+ * @param aPermissions unsigned long
+ * Unix-style permission bits to be applied to the new socket.
+ *
+ * Note about permissions: Linux's unix(7) man page claims that some
+ * BSD-derived systems ignore permissions on UNIX-domain sockets;
+ * NetBSD's bind(2) man page agrees, but says it does check now (dated
+ * 2005). POSIX has required 'connect' to fail if write permission on
+ * the socket itself is not granted since 2003 (Issue 6). NetBSD says
+ * that the permissions on the containing directory (execute) have
+ * always applied, so creating sockets in appropriately protected
+ * directories should be secure on both old and new systems.
