* On systems that don't support Unix domain sockets at all, this
* returns NS_ERROR_SOCKET_ADDRESS_NOT_SUPPORTED.
*
* 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.
*
* The |aPath| parameter must specify an existing directory entry.
* Otherwise, this returns NS_ERROR_FILE_NOT_FOUND.
*
* The program must have search permission on all components of the
* path prefix of |aPath|, and read and write permission on |aPath|
* itself. Without such permission, this returns
* NS_ERROR_CONNECTION_REFUSED.
*
* The |aPath| parameter must refer to a unix-domain socket. Otherwise,
* this returns NS_ERROR_CONNECTION_REFUSED. (POSIX specifies
* ECONNREFUSED when "the target address was not listening for
* connections", and this is what Linux returns.)
*
* @param aPath
* The file name of the Unix domain socket to which we should
* connect.
