Re: [MacRuby-devel] pointer to a pointer

[John Shea]

Hi Yehuda,

Laurent kindly responded to a similar query from me :

His reply (Novemebr 24th):

In order to use these methods I introduced in trunk a class named  
Pointer. You allocate a Pointer object by using the #new_with_type  
method in which you pass the Objective-C type encoding.  @ is for  
pointers, i for integers, d for doubles, etc...


# This is not very intuitive, I will implement the RubyCocoa way to  
deal with pointers as well.


You use it like that:

errorp = Pointer.new_with_type('@')
   urlData = NSURLConnection.sendSynchronousRequest(urlRequest,  
returningResponse:response, error:errorp)

   if urlData.nil?
 error = errorp[0]
 puts "error: #{error.description}"
  end



With trunk of last week it worked fine for me with:

errorp = Pointer.new_with_type('@')
response = Pointer.new_with_type("@")

urlData = NSURLConnection.sendSynchronousRequest(urlRequest,  
returningResponse:response, error:errorp)


Hope that helps,
cheers,
J

 I couldn't reproduce this. I'm using the most recent revision (r736).
