It's been a while, but my memory says that while memory-mapped files are great, *growing* memory mapped files was (significantly) less pleasant.
Growing a memory-mapped file *and keeping the entire file mapped into a single contiguous area* isn't very pleasant. If you don't have to keep the entire file mapped contiguously, it's much easier - ftruncate() to grow the file, and another mmap() call to map the new area on UN*X, probably similar calls on Windows. Using a mapped file as backing store for memory allocations shouldn't require a single contiguous area. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
