在没有标题的情况下调用c ++ dll中的函数

HMODULE hModule = LoadLibrary("your_dll_file_path.dll");

FARPROC function_address = GetProcAddress(hModule, "your_function_name");

typedef return_type (*function_pointer_type)(parameters);
function_pointer_type function_pointer = (function_pointer_type)function_address;

return_type result = function_pointer(parameters);

FreeLibrary(hModule);
