The NUC requestor encodes and decodes NetWare API calls to or from NCP requests. It maintains client connection information and provides transport for NCP requests to a network.
Applications using the NetWare API calls require that connections which the calls use remain available to them until they are no longer needed. The requestor must maintain this guarantee. The requestor will never disconnect a connection that is in use by any process. It, therefore, keeps accurate count of which processes are using a connection.
