Module handler 

PVA protocol handler — the core TCP connection processor.

handle_connection uses a SourceRegistry to resolve PV names across multiple registered sources, serving PVs over the EPICS PVAccess protocol.

Structs

ServerState

Shared server state that is passed to every connection handler.

Enums

PvListMode

Controls how the server exposes its PV directory.

Functions

bind_udp_search_socket

Bind the fixed UDP search port with SO_REUSEADDR (and SO_REUSEPORT on Unix) so other local PVA consumers such as p4p can also listen on the same well-known port. On macOS in particular, a plain UdpSocket::bind(5076) prevents any subsequent binder from joining the port, which broke co-located clients.

dump_hex_packet

handle_connection

Handle a single PVA TCP connection.
