How can I call a exported function using ordinal number
提问by Benjamin
If a dll exports some functions and the functions have only ordinal numbers, how can I call the functions?
如果一个dll导出了一些函数，而这些函数只有序数，我该如何调用这些函数？
Give me a short example please.
请给我一个简短的例子。

The documentation for GetProcAddressexplains that you pass the integer ordinal in the low-order word of the lpProcNameparameter. The MAKEINTRESOURCEmacro can actually be used to make this a little easier:
GetProcAddress的文档说明您在lpProcName参数的低位字中传递整数序数。该MAKEINTRESOURCE宏实际上可以用来轻松一点使这个：
int ordinal = 123;
HANDLE dll = LoadLibrary("MyDLL.dll");
FARPROC fn = GetProcAddress(dll, MAKEINTRESOURCE(ordinal));
