DMP文件的生成和使用

使用代码生成

主要函数: MiniDumpWriteDump

代码示例:

#include <stdio.h> #include <windows.h> #include <dbghelp.h> #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("%04d-%02d-%02d-%02d-%02d-%02d-%02d-%02d.dmp"), st.wYear, st.wMonth, st.wDay, st.wHour, st.wMinute, st.wSecond, st.wMilliseconds, rand()%100); 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.
