ABSTRACT:
A method and apparatus for arbitrating access to a shared resource in a system that does not support shared process space. An arbitrator process watches a port for an incoming call having associated therewith an identification string. When an incoming call is received, the identification string of the incoming call is compared to a set of identification strings corresponding to applications listening for an incoming call. If a matching string is located, the arbitrator process duplicates the handle to the port and passes the duplicated handle to the application corresponding to the matching string.
