[Boost-users] Boost thread questions

HI all, Thread support in boost is good. However, 1.- I don't see how to lock a file (fstream) for reading/writing. Do I have to use OS functions? 2.- How do I set a thread to be low priority? Do I have to go to the OS again? I think these are somewhat basic operations. If they are already implemented, can you tell me how to use them. If not, can you tell me if there are plans/steps taken to implement something like 'boost/filesystem/convenience.hpp' (a file with convenience operations). ++Hector C. ---------------------------------- --------------------------------- Yahoo!
