Detailed Description

Master control device for ObjDev.

Used primarily to create new objects via the ORBIOCCREATE ioctl.

Member Function Documentation

getDeviceNode()

uORB::DeviceNode * uORB::DeviceMaster::getDeviceNode

(

const char *

node_name

)

Public interface for getDeviceNodeLocked().

Takes care of synchronization.

Returns

node if exists, nullptr otherwise

printStatistics()

void uORB::DeviceMaster::printStatistics

(

bool

reset

)

Print statistics for each existing topic.

Parameters

reset

if true, reset statistics afterwards

showTop()

void uORB::DeviceMaster::showTop	(	char **	topic_filter,
		int	num_filters
	)

Continuously print statistics, like the unix top command for processes.

Exited when the user presses the enter key.

Parameters

topic_filter	list of topic filters: if set, each string can be a substring for topics to match. Or it can be '-a', which means to print all topics instead of only currently publishing ones.
num_filters
