/** Creates a block of shared memory. The first one to create the block sets the size
|
||
|
|
otherwise it is ignored. The block may be a different size than requested, especially
|
||
|
|
if it was already created.
|
||
|
|
|
||
|
|
On Unix based OSes, if a process using the block crashes, the block will leak. Clean
|
||
|
|
it up later with remove() and it will be deleted when the last process stops using it.
|
||
|
|
(No new processes will be able to attach)
|
||
|
|
|
||
|
|
On Windows the memory block will always disappear when the final process closes the
|
||
|
|
handle / crashes.
