Really, the crux of it is that functions specify what they're going to return. Since sometimes functions don't need to return anything, there has to be a way of specifying that, so you use "void". Note that omitting the RETURNTYPE attribute doesn't mean "i return nothing", it means "I may or may not return something, and I'm not telling you what it may or may not be", so you should always specify a return type on you functions.
To answer your specific questions, if you try and return something, an error will be thrown. You can still use the CFRETURN tag to exit the function at a place other than the end, you just can't return a value. cheers, barneyb On 6/26/05, Mike Kear <[EMAIL PROTECTED]> wrote: > I understand that a CFC method with returntype="void" isnt going to > send anything back, but what specifically does returntype="void" > mean? > > For example, does it mean that even if the function tries to return a > value it's not going to? or if it tries to return a value it'll throw > an error?
