Question

I m working on a project using libubox. And I have remarked that libubox execute functions in sequentiel mode and not in multthread mode.

Are there some one who could confirm this?

Answer 1

No, the libubox does not support multithreading

here after the justification of Felix (the Libubox developer)

Hello

I m contributing in the development of an opensource project which use
libubox. and I remarked that libubox execute handler functions in
monothread mode and not in muItithread mode.

1) so I m wondering if the libubox supports execution of handler in
multi thread mode ?

2) if yes how to activate multithread for registred handlers with libubox

3) if no. I m able to create 2 threads in my main program and then each
thread will call libubox functions to register handler function. Could
you give a quick how to do it with libubox? Hi,

uloop in libubox is currently not designed in a thread-safe way. I
would recommend running uloop in one thread only, and handing
processing for received events off to other threads. Would that be
enough for the needs of your application or do you need any specific
changes?

I have not really looked at thread-safe use of epoll yet (which is
used in uloop internally), I only remember some recent kernel related
discussion pointing out that its threaded use may be a bit tricky
because of some race conditions that were only fixed recently.
