OK, thank you. :)
I am curious about:
1. Does any lock-free containers for boost::interprocess (just like boost::lockfree)?
No.
2. Mutex and any other sync objects does not use native win32 API to implement. (It uses file to emulate that, right?)
Process-shared mutexes and condition variables and emulated using atomic operations and waits.
Does any performance impact in win32 platform to use locks?
If there is low contention, no. For high contention programs, spin-and-lock strategies can have a big performance impact.
Does anything I should notice to use boost::interprocess in win32 platform?
3. I should use lock for containers to implement multiple producer consumer, or just simply use message_queue for that? any good suggestion or recommend?
It depends on what you need (ordered that by a key, reallocation needs, etc.) Think about it just like you will think for inter-thread communications. best, Ion
