"Todd Niec" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED]Is it possible to use DmWrite() on ordinary memory? I have cases where buffers might be stored in "ordinary" memory (stack, heap, or static globals) or might be in a record in a file and I would like 1 method to write to both of them.
Try it and see. My suspicion is that is will probably fail, as DmWrite is designed to stop you from writing to the wrong place etc, but you never know...
Ugh, I can't believe that advice just crossed this forum! Using that logic, if I rob a house and don't get caught, it must be OK. :-)
See a posting I made to news://news.falch.net/pilot.programmer.gcc, 2003-03-06, "Re: Better ways to update a field" (sadly, it doesn't show up on a Google search). It's about DmStrCopy vs. StrCopy, but the same advice applies to DmWrite vs. MemMove.
Why can't you just keep track of the type of memory yourself, then use the appropriate DmWrite or MemMove calls? Even if DmWrite happens to work, it is always going to be slower than MemMove...
Now, *this* is advice I like! To it, I should add "Even if using DmWrite works on non-storage heap memory now, there's nothing that says it won't in the future".
