I've read through the man pages on mmap, munmap, and msync, and I still am not sure that I'm using the correct flags. Actually, I'm not even completely sure that mmap is the way to go. I'm creating a queue-like data structure that uses a fixed amount of heap space. When it fills up, it must dump itself to a file, and then it can consider itself "cleared", and continue adding elements. If a remove() call is made on the structure, and it's currently empty but has previously dumped to disk, it loads the data from disk, and then continues. Also, this is only a single-threaded application. I thought that I should use the MAP_PRIVATE flag when I map the file, then just munmap() then call close(fd) when I dump it, but that's not working. I'm just getting empty files. Is mmap even the way to go, or should I just be using write() and read()? -- Topher Fischer GnuPG Fingerprint: 3597 1B8D C7A5 C5AF 2E19 EFF5 2FC3 BE99 D123 6674 javert42@xxxxxxxxxx | http://www.thetopher.com
