While testing an updated version of nYume (aservia) I found that the program is leaking thread handles on Ms Windows. The program uses BeginThread and EndThread calls.
However, when I add CloseThread() right before EndThread(, the program no longer leaks handles. So, CloseThread may be needed on Ms Win machines. I don't think (all) the docs state to call closethread. If CloseThread should be called on Ms windows, then this makes cross platform threading difficult since windows requires something different than unix. I don't know if the object oriented TThread uses CloseThread in it's backend code and don't know if TThread leaks, I was just trying beginthread and endthread style. To find handle leaks, I simply use Windows Task Manager to monitor the processes, with the Handles column visible. I am also trying some other tools like DrMemory. First I thought I would post this to the mailing list to ask you what the proper way to program with threads is. If we must call closethread on MS Win machines but not unix machines, then something needs to change to make the threading in the RTL more cross platform (and all the docs would need to mention things about closethread if it is needed). The compiler is 2.4.2 and 2.4.4 that i am using. The documentation is here: http://www.freepascal.org/docs-html/prog/progse44.html#x217-23000010.2 But there is also more documentation elsewhere, such as the RTL docs. I guess I could look into Delphi to see how they use closethread. in their backend somewhere. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
