typedef void(__cdecl* DEBUG)();

int main() {
    HMODULE hModule = LoadLibraryA("HttCppLibrary.dll");
    if (hModule != NULL) {
        auto debug = (DEBUG)GetProcAddress(hModule, "DEBUG");
        debug();
        std::cout << "debug is called\n";
        FreeLibrary(hModule);
    }
    else {

Because obviously you'll need all the dependencies too?

Silme94OP•8mo ago

how do i do that

Buddy•8mo ago

Also if you are making a http library in C++, please don't require any .NET dependencies. Make it in pure C / C++

Silme94OP•8mo ago

uh not an easy task using socket to make http request

Buddy•8mo ago

Yes it is? Depends what features you need HTTP 1.1 is easy as hell

Silme94OP•8mo ago

well u have a lot to do, like parsing response headers but this isn't the issue why i shouldn't use

For one .. Runtime? It requires a lot of dependencies I highly doubt anyone will use said library if you need .NET dependencies. Most C / C++ devs will even only use header-only libraries Generally HTTP protocol is simple, it's all just text. https://osasazamegbe.medium.com/showing-building-an-http-server-from-scratch-in-c-2da7c0db6cb7

The latter is using Rust but the logic pretty much remains the same You just need to translate to C / C++
