Constructor & Destructor Documentation

xstream::dater::dater	(	std::streambuf *	sb,

construct using another streambuf

Parameters

sb	streambuf to write data to
format	format string for strftime defaults to [c] the preferred date and time representation for the current locale
separator	character that signal a change of line, defaults to newline
write_first	if true date is written right before the first write. default is true
