Whether this is triggered from Java, or you have some loop in your main thread that triggers this, is something that is in fact irrelevant for the functioning. I don't know enough about your architecture to comment on how to do it. I suspect though, that you will need to make it callable from Java and call it at regular intervals from Java code.

Michael is right, there's no *real* replacement, because modern OSes handle the memory differently, and the available memory can change anytime, even between or during the query function itself... But if you just want to get the code compiled, with the absolute certainity that it *will* break runtime, you can for MaxAvail just declare a dummy function which returns High(LongInt); or some other large constant. For MemAvail, the problem is that some code uses it to allocate all available memory in one go, this won't work. But you can still declare a dummy function, which returns 'some amount', so you can get the code compiled. However, the original functionality what this code does will not work, or will not work properly.

Re: [fpc-pascal] Java crash when fpc library CallVoidMethod in a thread.
Yep, yep, yep some very good news... 1) Added a new procedure in fpc library: = procedure uos_checksynchro(PEnv: PJNIEnv; Obj: JObject) ; cdecl; begin checksynchronize(); end; 2) And, of course, in fpc library exported as: = exports ... uos_checksynchro name 'Java_uos_checksynchro', ... 3) Added in Java wrapper class: public static native void checksynchro(); 4) In main Java application: After that the fpc thread (who does a CallVoidMethod) was called by Java (with uos.play(0);): = uos.checksynchro(); 5) And guess what... The CallVoidMethod is executed... So, first conclusion : it is possible to synchronize a CallVoidMethod inside a thread but Java main thread must call fpc-checksynchronize(). Hum, so maybe, (im new in Java) use a Java-timer who calls uos.checksynchro(); at regular time... 1) @ Ewald = Oops i read just your answer now, i will study it... 2) @ Ewald = i prefer your solution (if i can do it work) because i prefer not oblige Java-users to use a Java-timer. PS : All other solutions are welcome... PS2 : All those problems of synchronize CallVoidMethod inside a thread are problems only for uos (audio library). For fpGUI library, no any problems (because fpGUI library does not use threads...), those Java developers have now the best widgetset for their Java applications. PS3 : Hum, if one day, i need a fptimer in a fpc library, is it possible to use fptimer.ontimer who works with Java ? Many thanks.
