I see where you are coming from, but what I am getting at is, where in
the POSIX standard does it say that it needs to be anywhere in the file

Oh. It doesn't have to be a file. It can be a file. (And you can't asusme it's
not a file.)
Well, I am amazed. I guess I just have to do some more investigation
into workarounds for this, as RAM-based tmpfs file systems will get full
very quickly with shared memory segments, and large segments result in
high disk activity when munmap() is called. And SysV shared memory is
too limiting for my purposes.
Thanks for the info, Ted.
