#include <x/fd.H> #include <x/httportmap.H> #include <unistd.H> x::httportmap portmapper(x::httportmap::create()); x::fd socket=portmapper->connect("test.example.com", getuid());
This example creates a socket connection to an application socket named “test.example.com” running under the same userid. If there are more than one sockets registered under the same name and userid (if this application name is not exclusive), a connection gets established to one of them, at random.
x::fd socket=portmapper->connect_root("test.example.com");
connect_root() passes 0 for the userid parameter
to connect().
Userid 0 is root, and this example expects a root
process on the same server to have registered this application label,
which is connected to.
x::fd socket=portmapper->connect_any("test.example.com");
connect_any() connects to an application socket created
by a process with any userid.
Applications are responsible for implementing their own appropriate security. Any application can connect to any port, and the portmapper service will not prevent applications from connecting to application services running as a different userid.
#include <x/fd.H> #include <x/httportmap.H> #include <unistd.H> x::httportmap portmapper(x::httportmap::create("www.domain.com")); x::fd socket=portmapper->connect("test.example.com", 0);
This example creates a connection to a portmapper running on a different
server, www.domain.com, and connects to an instance of
“test.example.com” running on that server
as root,
instead of the same server as this application.
