Re: [Dev-C++] dynamic allocation and structs

[Per W. <pw...@ia...>]

Since this is Dev-C++, i.e windows programing.

The DLL is loaded in the memory space of your program. If multiple
applications links to the same DLL, the DLL with "switch" between each
applications memory space, depending on which application to make the
call.

The biggest problem with memory in a DLL is to have the DLL allocate C++
objects of new class types. You must export a static factory method, or
global function for the allocation.

There are a number of really good documents about this problem, but sorry,
I don't have them accessible right now.
