dump文件的生成和使用

主要函数: MiniDumpWriteDump

代码示例:

#include 
#include 
#include 

#pragma comment(lib, "Dbghelp.lib")

LONG WINAPI MyUnhandledFilter(struct _EXCEPTION_POINTERS *lpExceptionInfo)
{
LONG ret = EXCEPTION_EXECUTE_HANDLER;

TCHAR szFileName[64];
SYSTEMTIME st;
::GetLocalTime(&st);
wsprintf(szFileName, TEXT("d-d-d-d-d-d-d-d.dmp"), st.wYear, st.wMonth, st.wDay, st.wHour, st.wMinute, st.wSecond, st.wMilliseconds, rand()0);

HANDLE hFile = ::CreateFile(szFileName, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL );
if (hFile != INVALID_HANDLE_VALUE)
{
   MINIDUMP_EXCEPTION_INFORMATION ExInfo;

   ExInfo.ThreadId = ::GetCurrentThreadId();
   ExInfo.ExceptionPointers = lpExceptionInfo;
   ExInfo.ClientPointers = false;

   // write the dump

   BOOL bOK = MiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(), hFile, MiniDumpNormal, &ExInfo, NULL, NULL );

   if (bOK)
   {
    printf("Create Dump File Success!\n");
   }
   else
   {
    printf("MiniDumpWriteDump Failed: %d\n", GetLastError());
   }

   ::CloseHandle(hFile);
}
else
{
   printf("Create File %s Failed %d\n", szFileName, GetLastError());
}
return ret;
}

int main()
{
::SetUnhandledExceptionFilter(MyUnhandledFilter);

int a = 0;
int b = 2;
int c = b/a;

return 0;
}

使用:

把dmp文件和exe, pdb文件放在同一目录下, 然后用编译器(如vc)打开, 然后开始调试就会中断到刚才中断的地方.
