All variables have types in C. You can't declare a "void" variable. You can declare a void function. Try assigning it to a variable. You can't. void pointers (void*) are a different story.

So just the opposite of what the comment you replied to suggested:

'void' is a type, but in C values of the type void are not first class. Ie a function can return a value of type void, but you can't assign it to a variable.

I'm not sure what you mean, could you explain a bit more?

Are you saying void is not a type?
