visual studio 下 C++生成dump文件

1 lib配置 项目-->属性-->配置属性-->链接器-->输入-->附加依赖项 增加dbghelp.lib

2 头文件

#include <imagehlp.h>
#include <Windows.h>

3 main函数

在第一行调用window api：SetUnhandledExceptionFilter(UnhandledExceptionFilter2);

4 UnhandledExceptionFilter2的实现

LONG WINAPI UnhandledExceptionFilter2(struct _EXCEPTION_POINTERS* ExceptionInfo)
{
string strDumpFile = "exception.dmp ";
HANDLE hFile = CreateFile(strDumpFile.c_str(), GENERIC_WRITE, FILE_SHARE_WRITE, NULL, CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL, NULL );

if (hFile!=INVALID_HANDLE_VALUE)
{
MINIDUMP_EXCEPTION_INFORMATION ExInfo;

ExInfo.ThreadId = ::GetCurrentThreadId();
ExInfo.ExceptionPointers = ExceptionInfo;
ExInfo.ClientPointers = NULL;

// write the dump
BOOL bOK = MiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(), hFile, MiniDumpWithFullMemory, &ExInfo, NULL, NULL );
CloseHandle(hFile);
}
return EXCEPTION_EXECUTE_HANDLER;
}
