+   This utility function specifies a file descriptor to which a ``'\0'`` byte will
+   be written whenever a signal is received.  It returns the previous such file
+   descriptor.  The value ``-1`` disables the feature; this is the initial state.
    This is equivalent to :func:`signal.set_wakeup_fd` in Python, but without any
    error checking.  *fd* should be a valid file descriptor.  The function should
    only be called from the main thread.
