[Pythonmac-SIG] creating PyObjC wrapper for ObjC framework?

[has]

Hi all,

I'm trying to create a PyObjC wrapper for objc-appscript, and I'm  
wondering how to wrap methods that have NSError** arguments, e.g.:

@interface AEMEvent : NSObject {
	...
}
...

/*
  * Send event.

  * Parameters
  *
  * sendMode
  *    kAEWaitReply
  *
  * timeoutInTicks
  *    kAEDefaultTimeout
  *
  * error
  *    On return, an NSError object that describes an Apple Event  
Manager or application
  *    error if one has occurred, otherwise nil. Pass nil if not  
required.
  *
  * Return value
  *
  *    The value returned by the application, or an NSNull instance if  
no value was returned,
  *    or nil if an error occurred.
  *
  * Notes
  *
  *    A single event can be sent more than once if desired.
  *
  */

- (id)sendWithMode:(AESendMode)sendMode timeout:(long)timeoutInTicks  
error:(NSError **)error;

...
@end


The logical thing would be to convert a returned NSError into a Python  
exception, but BridgeSupport's gen_bridge_metadata tool doesn't seem  
to provide any help here, simply flagging the argument as 'opaque'.  
Any advice on how to proceed (with or without using BS)?

Thanks,

has
