如何在dll注入中调用特定函数？

以下代码将注入dll并将调用DllMain.我如何从DLL中调用特定函数,而不仅仅是DllMain？

    DWORD pid;
    HANDLE hd;
    LPVOID gp, rs, proc;

    gp = (LPVOID)GetProcAddress(GetModuleHandle(L"Kernel32.dll"), "LoadLibraryA");
    pid = 6096;

    hd = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);    


    rs = (LPVOID)VirtualAllocEx(hd, 0, sizeof(DLL_NAME), MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE);

    if (!WriteProcessMemory(hd, (LPVOID)rs, DLL_NAME, strlen(DLL_NAME), 0))
    {
        printf("WriteProcessMemory %d", GetLastError());
    }

    if (!CreateRemoteThread(hd, 0, 0, (LPTHREAD_START_ROUTINE)gp, rs, 0, 0))
    {
        printf("CreateRemoteThread %d", GetLastError());
    }

当您注入的DLL DllMain第一次运行时,调用CreateThread创建一个可以执行任何操作的新线程.请注意,您无法DllMain按照文档中的说明调用任意代码.因此CreateThread来自的呼吁DllMain.
