Update on Interprocess:
-> Due to Shmem problems with shared memory/named mutex/name semaphore lifetime between POSIX/Windows. I've decided to change Shmem approach (emulation of Windows lifetime behavior in POSIX with reference counting) to a POSIX lifetime (explicit unlinking shared memory).
This means that I have to rework all main classes to achieve POSIX persistence semantics in Windows even when a process crashes. This will require using memory mapped files to emulate shared memory (with some tricks to avoid performance problems with file-memory synchronization if it's possible). I think that this approach will be much more portable than the Shmem approach.
Well that move makes worries me. The use I currently put shmem/interprocess to is for high-speed IPC communications. Could you explain what the potential performance impact is with this change. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - grafikrobot/yahoo
