檢查dll是32位還是64位？

1. #include "stdafx.h"
2. #include <Windows.h>
4. int _tmain(int argc, _TCHAR* argv[])
5. {
6. BYTE buf[4];
7. FILE *fp = fopen("D:\\plugin_d.dll", "rb");
8. fseek(fp, 0x40-4, 0);
9. fread(buf, sizeof(char), 4, fp);
11. int a = int(buf[0]);
12. int b = int(buf[1])*256;
13. int c = int(buf[2])*256*256;
14. int d = int(buf[3])*256*256*256;
15. int sum = a+b+c+d;
16. fseek(fp, sum+4, 0);
18. BYTE bufMachine[2];
19. fread(bufMachine, sizeof(char), 2, fp);
21. int machine = (int)bufMachine[0] + (int)(bufMachine[1])*256;
23. if(machine == 0x14C)//332
24. {
25. printf("32 bit\r\n");
26. }
27. else if(machine == 0x8664)//34404
28. {
29. printf("64 bit\r\n");
30. }
31. else
32. {
33. printf("Unknow bit\r\n");
34. }
36. //system("pause");
37. getchar();
38. return 0;
39. }

檢測dll是32/64位？（直接讀dll文件包含的某幾個字節進行判斷）
