Here is the caller graph for this function:

timings_setup_tracing()

subroutine, public timings::timings_setup_tracing	(	integer, intent(in)	trace_max,
		integer, intent(in)	unit_nr,
		character(len=13), intent(in)	trace_str,
		character(len=default_string_length), dimension(:), intent(in), optional	routine_names
	)

Set routine tracer.

Parameters

trace_max	maximum number of calls reported per routine. Setting this to zero disables tracing.
unit_nr	output unit used for printing the trace-messages
trace_str	short info-string which is printed along with every message
routine_names	List of routine-names. If provided only these routines will be traced. If not present all routines will traced.

History

12.2012 added ability to trace only certain routines [ole]
