Re: [Boost-users] Interprocess: fixed_managed_shared_memory bug

Sunil Chomal wrote: [snip]

In priv_open_or_create() one creates the mapped_region which in turn calls mmap() to map the shared memory to the addr specified by us. However the mapped_region object that is created here is as follows:

mapped_region region(dev, read_write);

here the address is not passed to the to the mapped_region constructor, which has default arguments for addr which is '0'. Hence, the fixed_managed_shared_memory is never allocated at the addr specified.

A work around that I have done is to create the mapped_region as follows:

mapped_region region(dev, read_write, 0, 0, addr);

Yes, this is a bug. Thanks for pointing it. Your fix is correct. I will apply it to the CVS code. Thanks for the bug fix, Ion
