If I recall, the names for shm_open() are a bit goofy on the Mac. Try playing with the file name by removing the '/' or make it "/tmp/memfile". I use a guid for these things. I think removing the "/" is the key now I'm thinking about it.

Thanks for the tips! I tried them all and still no luck. The problem doesn't seem to be creating the file descriptor since I always get a valid file descriptor in return. The problem is writing to it. When I do a gzwrite() it returns that only 196,608 uncompressed bytes were written when it should be 827,326 bytes. If I do the same thing, only write to a normal file that has been created with "gzopen("tmpFile", "wb")" then everything works correctly.

I use a guid for these things.

What do you mean? You use a guid to name the file for shm_open()?

Thanks for your help!
