Detailed Description

Transport configuration for the qnx:// QNX native channel transport.

QnxConf binds the qnx:// URL scheme to the QNX Neutrino native IPC primitives (channels and connections). Messaging is performed directly through ChannelCreate / ConnectAttach / MsgSend / MsgReceive without any intermediate broker; this yields deterministic, low-jitter latency suitable for hard real-time workloads. The transport is available only when the binary is compiled for a QNX target.

Supported Node Types

Publisher	Subscriber	Server	Client	Getter	Setter
yes	yes	yes	yes	yes	yes

URL Format

qnx://<address>[?event=<name>]

Component	Description
address	QNX channel/topic name (URL host concatenated with path); not empty
event	Optional secondary event filter (?event=)

Channel / Connection Topology

Publisher / Server                            Subscriber / Client
------------------                            ------------------------
ChannelCreate(<address>)  <---- MsgSend ----  ConnectAttach(<address>)
        |                                              |
        v                                              v
   MsgReceive() loop                                MsgSend() / pulse

Example

auto pub = vlink::Publisher<MyMsg>::create_unique("qnx://control/cmd");
auto sub = vlink::Subscriber<MyMsg>::create_unique("qnx://control/cmd");

Note

Compiled only when VLINK_SUPPORT_QNX is defined.

QNX-only transport; not usable on Linux, Windows, or macOS hosts.

is_valid() returns false when address is empty.
