爱华网主要函数: 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("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_INFORMATIONExInfo;
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: %dn", GetLastError());
}
::CloseHandle(hFile);
}
else
{
printf("Create File %s Failed%dn", 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.
