strange catch clause... C++

What is this catch clause??

STD_CATCH_ALL_with_kMETHODID(...)

Its used in a python inter开发者_Python百科preter extension...

It's a macro so you need to look in your headers. An IDE should be able to go to its definition or look at the after preprocesser expansion. -E command line option on gcc

How about right-click and select Go To Declaration (using Visual Studio). You may try Go To Definition as well. If you cannot find it, it means you need to include a header where this macro is defined.
