Subject Re: MMAP support for APR
Date Fri, 15 Oct 1999 11:33:33 GMT

I don't think we want to use the API's that David has brought up for
shared memory.  We have a starting place already for shared memory, we
just need to figure out how to make it REALLY portable, which is why APR
doesn't support shared memory.  Take a look at the shmem directory.

I think the mmap work is simply designed to map a file into a memory
