Member Function Documentation

int VisAO::ShutterControlDioclient::init_shutter_open ( )

protected

The shutter will almost always be open (it fails open, etc.), this is just a check. so we don't want to count the cycle.

Definition at line 418 of file ShutterControlDioclient.cpp.

References VisAO::VisAOApp_base::write_fifo_channel().

int VisAO::ShutterControlDioclient::launchDataLogger ( )

protected

Sets to priority 0.

Return values

x	is the return value of pthread_create

Definition at line 560 of file ShutterControlDioclient.cpp.

References VisAO::__launch_data_logger(), and logger_th.

std::string VisAO::ShutterControlDioclient::auto_command	(	std::string	com,
		char *	seqmsg
	)

virtual

The handler always calls auto_command, which after app specific processing should call post_auto_command. This is so app specific processing happens first in auto mode, for speed.
