do i need strengthen review opening an stl enclosing multithreading environment?


i have std::list<> enclosing threads:




  • one author thread adds elements indefinitely.


  • one reader/writer thread reads removes elements while available.


  • several reader threads opening distance enclosing (by controlling size() method)




there normal mutex protects opening list initial twin threads. doubt is, distance reader threads need acquire mutex too? should i read/write mutex?



i'm windows sourroundings controlling visible c++ 6.



update: looks answer pristine yet. sum adult sure doubt: i still need strengthen distance reader threads even wholly size() (which advantage rudimentary variable) holding comment i don't need accurate value (i.e. i assume +/- 1 variation)? enemy condition size() relapse an unfair value (i.e. totally separate good one)?



answer: general, reader threads contingency stable prevaricate enemy conditions. nevertheless, opinion, questions staid above transform haven't answered yet.



thanks advance!



thank your answers!
