Visualc++ Exception Specifications

Exception Specifications This word I become "abnormal specifications", do not know whether accurate, there is more accurate hope that everyone Brin stimulation oh.

The exception specification is used to indicate what kind of exception a function can throw.

function can throw any type of exception

function cannot throw an exception

It is equivalent to

void __declspec (nothrow) MyFunction (int i) throw ();

Visualc++ with standard C + + in exception specification, below is the exception specification for visualc++

Exception specifications	Meaning
Throw ()	function does not throw an exception
Throw (...)	function can throw any exception
Throw (type)	function throws type exception

The behavior of a function that throws an exception also depends on the following factors:

• How to compile a function in C or C + +
• /EH compilation options (/EH: Exception handling Mode)
• The specified exception specification has a relationship
  

Here is a detailed description:

Function	/EHsc	/EHs	/EHa	/ehac
C function	Throw ()	Throw (...)	Throw (...)	Throw (...)
C + + function with no exception specification	Throw (...)	Throw (...)	Throw (...)	Throw (...)
C + + function with throw () exception specification	Throw ()	Throw ()	Throw (...)	Throw (...)
C + + function with throw (...) exception specification	Throw (...)	Throw (...)	Throw (...)	Throw (...)
C + + function with throw (type) exception specification	Throw (...)	Throw (...)	Throw (...)	Throw (...)
