Hi.

I understand your concern. But since I am working on a dynamic memory
management code that I wish to use with other projects that I have, I
didn't find appropriate to use shm_open.
Could you please provide a detailed list of the
problems you have with shm_open? If they are
valid, then I can bet the patch will be applied,
no matter what. :)
In fact there is a name associated with the shared memory requested with
shm_open, so that it can be mmap(ed) in another process. And I do not
wish to have it accessible by any other process, unless I choose to do so.
In this case you need to use shm_unlink() right
after shm_open(). Then this shm will be accessable
only to your process and its children, via an fd,
and not to anyone else. And you still can do anything
with it (ftruncate/mmap/mremap whatever).
And I think remap(ing) ANONYMOUS memory kind of make a lot of things easier.
In what way, exactly?
