Any task which is registered through nserve can be located through a call to one of these three functions:
IP_NserveLookup finds a task by name and has nserve fill in its structure.
IP_NserveLookupID finds a task by node, process and channel ID, and has nserve fill in its structure.
IP_NserveLookupName takes a name registered with nserve and fills in a new task structure for it.
