windows下c++程式碼儲存dump檔案
阿新 • • 發佈:2019-01-31
在main檔案,或者其他的檔案中新增如下程式碼:
#include "Windows.h" #include "DbgHelp.h" int GenerateMiniDump(PEXCEPTION_POINTERS pExceptionPointers) { // 定義函式指標 typedef BOOL(WINAPI * MiniDumpWriteDumpT)( HANDLE, DWORD, HANDLE, MINIDUMP_TYPE, PMINIDUMP_EXCEPTION_INFORMATION, PMINIDUMP_USER_STREAM_INFORMATION, PMINIDUMP_CALLBACK_INFORMATION ); // 從 "DbgHelp.dll" 庫中獲取 "MiniDumpWriteDump" 函式 MiniDumpWriteDumpT pfnMiniDumpWriteDump = NULL; HMODULE hDbgHelp = LoadLibrary(TEXT("DbgHelp.dll")); if (NULL == hDbgHelp) { return EXCEPTION_CONTINUE_EXECUTION; } pfnMiniDumpWriteDump = (MiniDumpWriteDumpT)GetProcAddress(hDbgHelp, "MiniDumpWriteDump"); if (NULL == pfnMiniDumpWriteDump) { FreeLibrary(hDbgHelp); return EXCEPTION_CONTINUE_EXECUTION; } // 建立 dmp 檔案件 TCHAR szFileName[MAX_PATH] = { 0 }; TCHAR* szVersion = TEXT("DumpDemo_v1.0"); SYSTEMTIME stLocalTime; GetLocalTime(&stLocalTime); wsprintf(szFileName, L"%s-%04d%02d%02d-%02d%02d%02d.dmp", szVersion, stLocalTime.wYear, stLocalTime.wMonth, stLocalTime.wDay, stLocalTime.wHour, stLocalTime.wMinute, stLocalTime.wSecond); HANDLE hDumpFile = CreateFile(szFileName, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_WRITE | FILE_SHARE_READ, 0, CREATE_ALWAYS, 0, 0); if (INVALID_HANDLE_VALUE == hDumpFile) { FreeLibrary(hDbgHelp); return EXCEPTION_CONTINUE_EXECUTION; } // 寫入 dmp 檔案 MINIDUMP_EXCEPTION_INFORMATION expParam; expParam.ThreadId = GetCurrentThreadId(); expParam.ExceptionPointers = pExceptionPointers; expParam.ClientPointers = FALSE; pfnMiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(), hDumpFile, MiniDumpWithDataSegs, (pExceptionPointers ? &expParam : NULL), NULL, NULL); // 釋放檔案 CloseHandle(hDumpFile); FreeLibrary(hDbgHelp); return EXCEPTION_EXECUTE_HANDLER; } LONG WINAPI ExceptionFilter(LPEXCEPTION_POINTERS lpExceptionInfo) { // 這裡做一些異常的過濾或提示 if (IsDebuggerPresent()) { return EXCEPTION_CONTINUE_SEARCH; } return GenerateMiniDump(lpExceptionInfo); }
int main()
{
// 加入崩潰dump檔案功能
SetUnhandledExceptionFilter(ExceptionFilter);
...;
}
PS:
1、可以選擇將dbghelp.dll檔案放入.exe目錄中
2、必須通過雙擊.exe的方式開啟應用程式,讓其崩潰退出,這樣才能產生dump檔案。如果是在vs下除錯,則由於會有崩潰彈窗提示,程式不會自動退出,所有不會產生dump檔案。這一點要注意,不能一沒有產生dump檔案,是覺得自己程式碼出問題了。
