Client

pvxs::client::Context represents a PVA protocol client. :

#include <pvxs/client.h>
namespace pvxs { namespace client { ... } }

Configuration

The recommended starting point is creating new context configured from $PVA_* environment variables. Use pvxs::server::Config::from_env() and then pvxs::server::Config::build().

EPICS_PVA_ADDR_LIST

A list of destination addresses to which UDP search messages will be sent. May contain unicast and/or broadcast addresses.

EPICS_PVA_AUTO_ADDR_LIST

If "YES" then all local broadcast addresses will be implicitly appended to $EPICS_PVA_ADDR_LIST "YES" if unset.

EPICS_PVA_BROADCAST_PORT

Default UDP port to which UDP searches will be sent. 5076 if unset.

using namespace pvxs;
auto ctxt = client::Confiig::from_env().build();

pvxs::client::Context

As an alternative to pvxs::server::Config::from_env() a Config may be created and filled in programatically.
