Represents a pre-computed event header that can be quickly written along with a hardware timestamp into the global trace.
val create_duration :

t * tReturns a separate duration begin and end events, with matching name and category. arg_types are attached to duration begin event only. Duration end event does not have any arguments. create_duration_begin and create_duration_end allow different arguments for begin and end events, but the user must ensure the name and category match.
