获取DLL函数的内存地址

问题描述：

我想知道是否可以使用C和WindowsAPI，是否有一个函数可以让我获得dll中某个函数的32位(我认为)内存地址.例如.如何在kernel32.dll中获取Beep()的32位$ xxxxxxxx地址.其次，如果我在汇编中使用内存地址而不是函数名，可以避免链接.例如

I want to know if it is possible, using C and the WindowsAPI, if there is a function that will get me the 32 bit(I think) memory address of a function in a dll. For example. How do I get the 32 bit $xxxxxxxx address of Beep() in kernel32.dll. Secondly, if I use the memory address instead of the function name in assembly, can I avoid linking. For example

mov eax, $xxxxxxxx

代替

mov eax, Beep

答

该程序将在kernel32中打印Beep的地址:

This program will print the address of Beep in kernel32:

#include <windows.h>
#include <stdio.h>

int main(void)
{
    HMODULE hMod = GetModuleHandle("kernel32.dll");
    void* fn = GetProcAddress(hMod, "Beep");
    printf("%p", fn);
}

为简单起见，我省略了错误检查.在真实程序中，您不会这样做.

I omitted error checking for the sake of simplicity. In a real program you would not do so.
