在Windows/QT环境编程中同时catch C++异常和SEH异常

代码如下：

//.h

class CExceptionGuard
{
public:
	CExceptionGuard();
	~CExceptionGuard();
private:
	class Impl;
	Impl* prd;
};


// .cpp
class SE_Exception : public std::exception
{
private:
	const unsigned int nSE;
public:
	SE_Exception() noexcept : SE_Exception{ 0 } {}
	SE_Exception(unsigned int n) noexcept : nSE{ n } {}
	unsigned int getSeNumber() const noexcept { return nSE; }
};

void trans_func(unsigned int u, EXCEPTION_POINTERS*)
{
	throw SE_Exception(u);
}

class Scoped_SE_Translator
{
private:
	const _se_translator_function old_SE_translator;
public:
	Scoped_SE_Translator(_se_translator_function new_SE_translator) noexcept
		: old_SE_translator{ _set_se_translator(new_SE_translator) } {}
	~Scoped_SE_Translator() noexcept { _set_se_translator(old_SE_translator); }
};

class CExceptionGuard::Impl
{
public:
	Impl() {};
	Scoped_SE_Translator scoped_se_translator {	trans_func};
};

CExceptionGuard::CExceptionGuard()
{
	prd = new Impl;
}
CExceptionGuard::~CExceptionGuard()
{
	delete prd;
	prd = NULL;
}
