Member Function Documentation

library_available()

bool pulp::runtime::UdevMonitor::library_available ( )

static

True iff libudev can be loaded right now (Linux dlopen probe).

Always false on non-Linux. Cheap; does not start a monitor.

operator=()

UdevMonitor & pulp::runtime::UdevMonitor::operator= ( const UdevMonitor & )

delete

running()

bool pulp::runtime::UdevMonitor::running ( ) const

inline

start()

bool pulp::runtime::UdevMonitor::start	(	const std::vector< std::string > &	subsystems,
		ChangeCallback	on_change )

Begin watching subsystems (e.g.

{"sound"}). on_change fires on a dedicated monitor thread for each add/remove. Returns false (starting nothing) on non-Linux, when libudev is unavailable, or when the netlink monitor can't be set up. A second start() while running is a no-op false.

stop()

void pulp::runtime::UdevMonitor::stop

(

)

Stop the monitor thread and release handles.

Safe when not running and from the destructor; idempotent.
