Dynamic Windows API Resolver

A simple single-include utility that makes runtime winapi resolving a breeze. Using LoadLibraryA and GetProcAddress manually each time you want to use an api can be cumbersome and error-prone, especially with the need to repeatedly cast function pointers to the correct types. This project aims to take away that complexity.

Usage

#include <iostream>
#include "resolver.hpp"

int main(int argc, char* argv[]) 
{
    auto pMessageBoxA = WinApi("user32.dll", MessageBoxA);
    if (!pMessageBoxA) {
        std::cerr << "Failed to resolve api" << std::endl;
        return -1;
    }

    pMessageBoxA(NULL, "hello world", "hello world", MB_OK);
}

The following image shows the import directory of the output executable in CFF Explorer 🌶

As you can see - user32.dll is not found under the Module Name column.
