cdecl on the web

cdecl is a really useful tool for working out what a C type declaration is in English. For example:

const char** x

is translated into

declare x as pointer to pointer to const char

That is a very simple example, but it really comes into its own when given something nasty, like this:

char (*(*x())[5])()

which is:

declare x as function returning pointer to array 5 of pointer to function returning char

And you can go the other way too:

declare x as pointer to const pointer to int

becomes:

int * const *x

Which is all rather nice.

What is really useful is that it is available online at http://www.cdecl.org.
