Library initialization for rpcref.dll --
|
|
This Dll adds a ref count around the RPC runtime call -
|
|
RpcServerListen(). This enables multiple services in
|
|
the inetinfo process to do a RpcServerListen() without
|
|
stomping over each other.
|
|
|
|
This Dll will maintain a ref count on calls to RpcServerListen()
|
|
and call RpcMgmtStopServerListening() when the ref count goes to 0.
