Why does std::exception constructor specifies it can throw any ?

by: Pierre Rouleau | last post by:

The std::exception class defined in the Standard C++ <exception> header specifies that the constructors could throw any exception becuase they do not have a throw() specification. Why is that? Is this because there could be an exception thrown when the code creates a std::exception? I would assume that is not the case. However, if I want to create a new exception class, derived from std::exception (say MyException) then how can I...

Is throw specification necessary?

Hi: In recent pondering, I am begining suspecting the usefulness of throw specification in the language(I know this opinion have long existed), even for delete!. The primary reason is that reimplementing such members or functions cannot throw any types other than specified (what would be the justifiable reason?

CryptoStream calls Write when it shouldn't

by: Daniel Weber | last post by:

Hi! In my code I create a CryptoStream around another stream of my own, with CryptoStreamMode.Read. So I just can read from the CryptoStream. When I close that CryptoStream, however, the underlying stream's Write() method is called, with an empty buffer (offset and count-parameters are also 0). My streams' CanWrite property returns false, so the CryptoStream should not call Write(). It shouldn't call Write() at all, because I created it...

raise or throw

by: Frank | last post by:

Hi, what should I use to raise an error: RAISE or THROW And I am asking this with regard to the future VB.NET developments. Is Raise the old way and Throw the new? Throw does not have parms to put errortext in it, so it seems less usable then raise. I am looking forward to your opinions.Refs to websites about this are welcome.

The FAQ at http://www.parashift.com/c++-faq-lite/exceptions.html#faq-17.6 says that you shouldn't throw built-in exceptions. I'm not sure why I shouldn't throw something like std::domain_error though -- if it does all that I want it to do. Joe

why a member "swap" function shouldn't throw?

by: Jess | last post by:

Hello, It is said that if I implement a "swap" member function, then it should never throw any exception. However, if I implement "swap" non- member function, then the restriction doesn't apply. Can somebody tell me why? Thanks, Jess
