void DimServiceInfoList::SendDimCommand	(	const std::string &	server,
		std::string	str,
		std::ostream &	lout
	)		const

Tries to send a dim command according to the arguments. The command given is evaluated according to the available format string.

Parameters

server	The name of the server to which the command should be send, e.g. DRIVE
str	Command and data, eg "TRACK 12.5 13.8"
lout	the ostream to which errors and debug output is redirected

Exceptions

runtime_error

if the server or command was not found, or if the format associated with the command could not be properly parsed, or if the command could not successfully be emitted.
