All we FLTK user need a timer, like wxTimer class (wxWidgets) perhaps. I
am joking...
I think i'll follow Ian tip, in which he explains me the situation in which:
When you need to start a thread to do some work in the background
(e.g. your recorder) you put it in a void function like this...
void my_thread_function(void) {...}
And you start that from your main thread like this...
_beginthread(my_thread_function, 0, NULL);
(under unix use pthread_create(...) instead)

Thanks, i'll TRY to remember this tip too, Ed ;-)
