Deletes the entire service context list for an object.
A service context list is held globally for a CORBA object. This means that the service context list is sent unchanged with every IiopRequest function call, unless a new service context list is created, using the functions IiopBeginServiceContext, IiopEndServiceContext, IiopSetServiceContext or IiopDeleteServiceContextList.
However, if a service context list is defined for a callback object using the same functions, it is bound to a special operation defined by IiopObjectListen. Any time this operation is invoked by the server, Silk Performer returns the service context list along with the IIOP reply message.
IIOP.bdh
IiopDeleteServiceContextList( in hIiop: number ): boolean;
true if successful
false otherwise
