Dynamically loading a DLL twice

[Adrian_F_1]

I have in my Fortran code:

        dll_handle = LoadLibrary('Test123.dll'//char(0))

However this Fortran code may also be called from a C++ wrapper which may have already dynamically loaded this DLL.  From a quick test the Fortran call does not simply return the handle that the C++ wrapper got when it loaded it, but returns a different handle.  Has the DLL been loaded twice?  If so is this a problem?

Apologies it does seem to use the same handle.  I was looking at what the C++ variable was pointing to rather than the variable itself which is of HMODULE type which apparently is a pointer of type pvoid (defined as typedef void *PVOID;)

I guess the Fortran variable dll_handle, declared as integer, is also one of these.

Make sure the Fortran variable is declared integer(HANDLE), not just integer.
