Re: Solaris Question (fwd)

Looks like somethign top secret. :) Usually stuff like this will get
documented in the next release.
And rememeber...you did not hear it from me....
"Doors" are a new fast local IPC mechanism in Solaris 2.5. Doors are faster
than any other local IPC, including unix domain sockets. I believe the program
interfaces for using doors are undocumented in Solaris 2.5, but there are a
few services that use them. One of these is the name service cache daemon
(/usr/sbin/nscd - see nscd(1m)). The front-end library function
gethostbyname() and gethostbyaddr() make a door call to the nscd process, which
does the actual DNS lookup, and caches the result for other applications to
use. That file "/etc/.name_service_door" is the filesystem entry for the door
that the library function uses to talk to the nscd process.
