如何获取当前DLL的目录

Question

I will build c-shared in golang -o config.dll .

Let's say the directory is c:\\test\\config.dll

In mail.dll, I'm going to open a configuration file. This file is in the directory of config.dll. c:\\test\\config.json

I'm calling it in c++ c:\\test\\c++.dll .

In c++ I use

{ // NB: XP+ solution!
    HMODULE hModule = NULL;
    GetModuleHandleEx(
        GET_MODULE_HANDLE_EX_FLAG_FROM_ADDRESS,
        (LPCTSTR)GetCurrentModule,
        &hModule);

    return hModule;
}
WCHAR path3[MAX_PATH + 1] = { 0 };
        HMODULE hm = GetCurrentModule();
        ::GetModuleFileName(hm, path3, MAX_PATH);
        PathRemoveFileSpec(path3);
// path3 c:\test\c++.dll

What is the equivalent of this in Go?

I try to use

os.Getwd()
runtime.Caller(1)
os.Args[0]
os.Executable()

I want to get directory c:\\test\\

您可以使用 cgo 在它存在的任何库中调用相同的函数。
