The library does not dictate any thread model. To embed the library to your application you should choose
appropriate implementation of \p cds::threading::Manager interface
or should provide yourself.
- The \p %cds::threading::Manager interface manages \p ñds::threading::ThreadData structure that contains GC's thread specific data.
+ The \p %cds::threading::Manager interface manages \p cds::threading::ThreadData structure that contains GC's thread specific data.
Any \p cds::threading::Manager implementation is a singleton and it must be accessible from any thread and from any point of
your application. Note that you should not mix different implementation of the \p cds::threading::Manager in your application.
