Detailed Description

Function Documentation

NT_AddLogger()

NT_Listener NT_AddLogger	(	NT_Inst	inst,
		unsigned int	min_level,
		unsigned int	max_level,
		void *	data,
		NT_ListenerCallback	func )

Add logger callback function.

By default, log messages are sent to stderr; this function sends log messages to the provided callback function instead. The callback function will only be called for log messages with level greater than or equal to min_level and less than or equal to max_level; messages outside this range will be silently ignored.

Parameters

inst	instance handle
min_level	minimum log level
max_level	maximum log level
data	data pointer to pass to func
func	listener callback function

Returns

Listener handle

NT_AddPolledLogger()

NT_Listener NT_AddPolledLogger	(	NT_ListenerPoller	poller,
		unsigned int	min_level,
		unsigned int	max_level )

Set the log level for a listener poller.

Events will only be generated for log messages with level greater than or equal to min_level and less than or equal to max_level; messages outside this range will be silently ignored.

Parameters

poller	poller handle
min_level	minimum log level
max_level	maximum log level

Returns

Listener handle
