Sorry Bernie.

I just realized that I didn't really answer your questions.
That was an oversight on my part.  I read fast and didn't think.

The star is akin to @ symbol in that it is requesting the address of the
variable.
Many times a *void can be considered a general pointer but not always,
it depends on the context.

Let's take fn GetControlProperty() as an example.

Here's how it appears in Apple's header:

extern OSStatus
GetControlProperty(
   ControlRef   control,
   OSType       propertyCreator,
   OSType       propertyTag,
   UInt32       bufferSize,
   UInt32 *     actualSize,
   void *       propertyBuffer)


and this is how it has been translated in FB:

toolbox fn GetControlProperty(
   ControlRef c,
   OSType propertyCreator,
   OSType propertyTag,
   UInt32 bufferSize,
   UInt32 *actualSize,
   ptr *propertyBuffer ) = OSStatus


Questions:

1) What is the * (star) for in "UInt32 * actualSize"? Do we need it in
the FB translation?

2) Is it fair to say that whenever the param type appears as "void", we
can substitute "ptr" ?


TIA
Bernie
