<sys/cdefs.h>,
<Carbon/Carbon.h>
GrowlApplicationBridge uses a delegate to provide information //XXX
to Growl (such as your application's name and what notifications it may
post) and to provide information to your application (such as that Growl
is listening for notifications or that a notification has been clicked).
You can set the Growldelegate with Growl_SetDelegate and find out the
current delegate with Growl_GetDelegate. See struct Growl_Delegate for more
information about the delegate.
