Re: [boost] [shmem] New Shmem snapshot available in boost vault

Thanks for the props!

 I will try to use gcc 3.3 in linux to detect this type of warnings. It is 
just that I always rely (wrongly) on typedef inheritance when using 
templates, so I will have a look. For the next snapshot I plan better 
documentation and shmem::deque. However, my main concern is to have a 
portable shared memory management between posix (shm_open, shm_ulink, 
shm_close) and Win32. For the moment I have no solution to this, and I have 
looked into several open source libraries to take ideas, but apart from 
using memory mapped files, I don't see any solution.

  Does anyone know a portable shared memory implementation that behaves 
equally (I mean, when creating and destroying) in Win32 and Unix?

Regards,

 Ion
