This function will call lwevent_wait() in a loop forever. The loop can be aborted by setting the

flag lwevent_loop_exit to non-zero. The loop will also be aborted if lwevent_wait() returns an
|

flag \ref lwevent_loop_exit to non-zero. The loop will also be aborted if lwevent_wait() returns an
|

error (in which case \a errno can be used to determine the error).
