[fpc-devel] How to clearly shutdown ThreadManager

[Petr Kristan]

Hi.

If I check my multithreaded program with valgrind in linux I get these
memoryleaks:

==27262== 32 bytes in 1 blocks are still reachable in loss record 1 of 2

IMHO it is because CThreadManager.DoneManager (calls UnLoadPthreads) is not called at the end
of program.

Is any way how to shutdown threading and satisfy valgrind by dlclose()?

Thanks
