Title: Handy tool for C coders
Post by: Karlos on August 29, 2011, 03:53:15 PM

After some time messing around with lesser languages, I found I forgot some of my C declaration syntax for some of the more exotic pointer types.

Anyway, I stumbled (actually, now that I think about it, I recall that maybe nicholas mentioned this one to me before) across the following site which is quite handy:

http://cdecl.org/

Enjoy :)

I remember seeing this on a Fred Fish disk many years ago.  It's cool that they made a web site version though.

What does (^) mean?

It's an exclusive or operator but the program on the website only covers variable declarations.

The 3rd example disgorges the following rumination:

Code: [Select]

(double (^)(int , long long ))foo

I don't understand.

Don't feel bad about that, it's not remotely standard C syntax, rather an Apple extension to C, called "blocks" which aim to mirror the functionality of lambda expressions in more recent languages.
