C++ FilePtr::writeLine方法代码示例

		// NEW FUNCTIONALITY!!!
		// 
		// Each file may have a number of files open as children which
		// use the parent's handle for reads and writes.  This would
		// allow us to open a packet file and read a packet as a fitIni
		// or allow us to write a packet as a fit ini and so forth.
		//
		// It also allows us to use the packet file extensions as tree
		// files to avoid the ten thousand file syndrome.
		//
		// There is now an open which takes a FilePtr and a size.
		// 
		// IF a numChild parameter is passed in as -1, we want this file in RAM!!
		// This means NO CHILDREN!!!!!!!!!!!!!
