116 Data Path Routing (DPR) HighWire MTP-2 - 1.2, September 4, 2002
7-2. libdpr (3sbe)
libdpr provides a set of routines that allow an application to set up and
dynamically control time slot connections and clocking operations on all
HighWire boards. The DPR service included in the protocol modules
downloaded to the HighWire board initializes the Data Path Routing matrix to
a functional default configuration. This configuration may be changed by
using the getmsg(2) and putmsg(2) Streams functions as described in
Section 7-1, dprservice (7D), or by using the routines defined in this chapter
that are included in the shared object library libsbe.so.
For additional information on shared object interfaces, see intro(4). The
features in this library are implemented upon dynamic linking.
To reference the online manpages, you may need to use the appropriate
man(1) section.
