Function Documentation

◆ publishDiagnosticSafe()

bool publishDiagnosticSafe	(	const char *	eventName,
		const char *	data,
		PublishFlags	flags )

Publish a state transition to the log handler.

Safely publish diagnostic message through queue with depth guard.

Routes low-priority diagnostic messages through PublishQueuePosix only when queue depth is below threshold, preventing displacement of critical telemetry data during tight loops or error conditions.

Parameters

eventName	The event name for the publish.
data	The event data payload.
flags	Particle publish flags (e.g., PRIVATE).

Returns: true if message was queued or published, false if queue was too full.
