How do I import a DLL (minifmod.dll) in C++ ?
I want to be able to call a function inside this DLL. I already know the argument list for the function but I don't know how to call it.
Is there a way of declaring an imported function in C++ like in C# ?
回答1:
The c# syntax for declaring an imported function is not available in c++. Here are some other SO questions on how to use DLLs:
- Explicit Loading of DLL
- Compile a DLL in C/C++, then call it from another program
- Calling functions in a DLL from C++
- Call function in c++ dll without header
- How to use dll's?
- Is this a good way to use dlls? (C++?)
回答2:
If the DLL includes a COM type library, you can use the #import statement as such:
#import dllname.dll
Otherwise, you'll need to link with an import library, and you'll need to provide a function prototype for your compiler. Typically the import library and a header file with the prototypes are provided by the DLL developer. If you're not, they can be very difficult to produce - unless you already know the argument list for the function, which you say you do. Instructions can be found here, amongst other places.

At runtime you can call LoadLibrary() and then call GetProcAddress() to access the function from a DLL. You will need to cast this address to a prototype you define with typedef . See the example at GetProcAddress documentation page.
