Hi, What is the procedure when linking a shared library to get a piece of data (e.g. a handle to a hardware resource) to be shared by all processes that link to the shared library? Any help will be appreciated. Roger Wells, P.E. SAIC 221 Third St Newport, RI 02840 401-847-4210 (voice) 401-849-1585 (fax) roger@mtg.saic.com
