I'm aware of that issue. Unfortunately, there's no solution without threads, yet. My solution in XDirectFB is to create a thread which fetches events from the event buffer and writes them into a pipe. The read file descriptor is then added to the fileset. You can read DFBEvent's from that pipe and process them. More straightforward would be a function of the event buffer which creates the pipe itself and returns the read file descriptor to the application. The event buffer will then write to the pipe itself. This saves one thread and the overhead of the indirection. > P.S.
