Re: [Mingw-users] Q: DLL that can be dynamically loaded at the run time?

You are missing something about using a DLL loaded with
LoadLibrary and of course how functions whose addrs are
retrieved by GetProcAddress are used.

Wether or not there exists a DllMain is completely irrelevant
to you (from a point of loading the DLL). That is taken care
of by LoadLibrary (and -of course- the creator of the DLL).

You just load the DLL with LoadLibrary and use the returned
HANDLE to load the Addrs of the functions you wish to call by
using GetProcAddress. The resulting function ptrs are used
just like "normal" functions.

You definitely should RTFM, e.g. MSDN.
You may as well check the archive of this list as this very
topic had occasionally been discussed over the years.

Last not least I'm sure resorting to google will give you
plenty of advice as well.

> How to create such Win32 DLL using mingw?

Your problem is not _creating_ such a DLL as it is created like
any other DLL - it is in fact not a special DLL in any way.

Your problem is that you do not yet seem to understand how this
dynamic loading and retrieving addrs from the DLL at runtime
works.

HTH, best,
