Detailed Description

a small object that represents a stack trace in progress.

the object will automatically be destroyed when the containing scope exits. this enables a users of the stack tracker to simply label their function name and get the frame added. if they want finer grained tracking, they should update the line number periodically through their function, especially when memory is about to be allocated or where something might go wrong.

Constructor & Destructor Documentation

frame_tracking_instance() [1/2]

application::frame_tracking_instance::frame_tracking_instance	(	const char *	class_name = "",
		const char *	func = "",
		const char *	file = "",
		int	line = 0,
		bool	add_frame = false
	)

as an automatic variable, this can hang onto frame information.

if "add_frame" is true, then this actually adds the stack frame in question to the tracker. thus if you use this class at the top of your function, such as via the FUNCDEF macro, then you can forget about having to pop the frame later.
