Doubt in prototype declaration.

[mthread]

Hi,
I came across this prototype declaration

virtual const char* what() const throw()

I would like to know what is the purpose of last two words 'const
throw()'

'const' associated with the function declaration (in a class) promises
that this function is not going to alter any of the non-static class
members(data). 'throw()' says that this function won't throw any
exception. You can also refer to your favourite C++ book.
