Class Methods

checkInPort:withName:

+ checkInPort:(NXPort *)port withName:(const char *)aName

Makes the NXPort object port available with the name aName.  Returns self if the port is successfully checked in, nil otherwise.

checkOutPortWithName:

+ checkOutPortWithName:(const char *)name

Removes the port identified by name from the Network Name Server; the port can be removed only by the application that checked it in.  Returns self if the port is successfully removed, nil otherwise.

lookUpPortWithName:

+ (NXPort *)lookUpPortWithName:(const char *)name

Returns an NXPort object for the port registered (via the Network Name Server) on the local machine under the name name, or nil upon failure.

lookUpPortWithName:onHost:

+ (NXPort *)lookUpPortWithName:(const char *)name onHost:(const char *)hostName

Returns an NXPort object for the port registered (via the Network Name Server) on host hostName under the name name, or nil upon failure.  If hostName is ª*º the search will be conducted for each host on the subnet, although this might take a bit of time.
