This package contains the implementation of the Curry Port Name Server (CPNS) and related libraries.
The CPNS is used to implement libraries which supports network connections over ports with symbolic names.
To implement a connection to a port with symbolic name
pn, CPNS (running on the remote machine of
pn) is asked to get the physical socket number of this port. In order to connect to CPNS from any machine in the world, the CPNS demon always listens at the port
Network.CPNS.cpnsSocket, which is defined as
curry-cpnsd installed by this package is the CPNS demon. It understands the following commands:
Start the CPNS demon on the local machine:
Usually, this is automatically done when a new port is registered.
Terminate the CPNS demon on the local machine:
Usually, this is not necessary...
Show status information (memory and currently registered ports):
Exits with error message and status if CPNS demon is not running.
Show the complete log file:
/tmp/Curry_CPNSD.log : the log file of CPNSD
The implementation uses the following system commands:
touch chmod ps nohup lockfile-create lockfile-remove
