WinCE下查看函数调用堆栈

http://www.cnblogs.com/opc521/archive/2010/04/08/1707060.html

1. 获得函数调用堆栈地址

   WinCE下可以通过函数GetCallStackSnapshot()来获得函数调用堆栈地址。该函数在pkfuncs.h中定义。

   文件路径：

   c:\Program Files\Windows CE Tools\wce600\PanelViewPlus SDK\Include\X86\pkfuncs.h

   函数定义：

   ULONG GetCallStackSnapshot (ULONG dwMaxFrames, CallSnapshot lpFrames[], DWORD dwFlags, DWORD dwSkip);

      

   dwMaxFrames： 最大堆栈的个数

   lpFrames： 返回堆栈的数组

      

   其中 CallSnapshot定义：

   typedef struct _CallSnapshot {

   DWORD dwReturnAddr;

   } CallSnapshot;

   dwReturnAddr 为函数返回地址， 通过该地址结合map文件就可以找到调用的函数名。

      

   例子：

   #define MAX_FRAME_COUNT 10

   CallSnapshot lpFrames[MAX_FRAME_COUNT];

   int nRet = GetCallStackSnapshot(MAX_FRAME_COUNT, lpFrames, 0, 1);

      

      

2. MAP  文件

   MAP 文件是程序的全局符号、源文件和代码行号信息的唯一的文本表示方法，它可以在任何地方、任何时候使用，不需要有额外的程序进行支持。 MAP文件可以在Visual Studio中设置，在编译工程的时候产生：

                       

生成的MAP文件可以指定名称，如不指定则为工程名字，扩展名为.map。

   

打开map文件可以看到为如下格式：

(其他部分省略)

   

最后一行，可以看到函数名（OnBnClickedButton1），类名(CTestClientDlg)，后面是地址(00401450)，最后是cpp编译出来的obj文件名。

在第一部分我们已经通过GetCallStackSnapshot（）获得函数的返回地址，根据这个地址到map文件中查找相等或者比它小的第一个地址处的函数名就是当前调用的函数。

   

微软提供开源代码mapfile.c用来方便的读取map文件:

www.totalembedded.com/open_source/objtool/objtool/mapfile.c

   

其中函数

PSTR MapfileLookupAddress(

IN PCWSTR wszModuleName,

IN DWORD dwAddress, DWORD* pdwResult)；
