driverStatus()

ChannelManager::DriverStatus fl::ChannelManager::driverStatus

(

const fl::string &

name

)

const

Look up a driver's registration status without logging on miss.

Parameters

name	Driver name (case-sensitive)

Returns

DriverStatus tri-state (NOT_REGISTERED / STATUS_DISABLED / STATUS_ENABLED)

Note

Companion to findDriverByName() — same silent-on-miss behavior. Used by Channel::showPixels() to detect the #2517 silent-drop case (enqueued data routed to a disabled / unregistered driver).
