I am writing a program that is meant to be extended by some function definitions. One of the way of compiling the program is to create a single executable linking your code to the main code. The problem is: one of the function to define is optional and I need to test for that. On Linux, here is what I am doing: Compile the program with...
Basically I have a header file like this: #if WIN32 typedef DWORD (WSAAPI *SocketStartup) (WORD wVersionRequested, LPWSADATA lpWSAData); typedef SOCKET (WINAPI *MakeSocket)(IN int af, IN int type, IN int protocol, IN LPWSAPROTOCOL_INFOW lpProtocolInfo, IN GROUP g, IN DWORD dwFlags ); typedef DWORD (WINAPI *SocketSendFu...
I have the following items in a structure - Dll name (absolute/relative path) - Function name in the dll - number of parameters - Array of parameter types and values With these information, I need to load the dll and call the function. To load the dll - I would use loadlibrary To get the address of the function - I would use GetProcAdd...
I've done some googling but haven't really found much. How does GetProcAddress work? What goes on behind the scenes? Do the method names and their corresponding address get stored in meta data somewhere? ...
Is there a way to load a 32bit DLL library (something with the same usage as LoadLibrary) I would like to use that function along with GetProcAddress. I looked at WOW, but it does not seem to offer the functionality. The functionality should exist, since tools like DependencyWalker are able to read the symbols of a 32bit dll even though...
I made a DLL with a function named "render()" and I want to load it dynamically to my application, but GetProcAddress cannot find it. Here's the DLL .h: #ifdef D3D_API_EXPORTS #define D3D_API_API __declspec(dllexport) #else #define D3D_API_API __declspec(dllimport) #endif D3D_API_API void render(); And here's DLL .cpp: #include "std...
I am trying to call functions located in an external DLL from a C++ 6.0 MFC application. I do not have the def or the lib file for this DLL, so I am using LoadLibraryEx/GetProcAddress methodology to access the routines I need to use. I have used DumpBin to get the exported names of the routines I wish to use. When the program executes...
Hi. First, I know that it doesn't make sense to compare the dllimport attribute and the getProcAddress function directly. Rather, I am interested in comparing two pieces of code, that achieve basically the same thing - calling a function in a dll - by either importing the function with the dllimport attribute or with the getProcAddress ...
For some reason, whenever my C# .NET 2.0 application makes a call to GetProcAddress it always returns zero. public class MyClass { internal static class UnsafeNativeMethods { [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)] internal static extern IntPtr LoadLibrary(string lpFileName); ...
