pre-processing before it runs 471 the Code/Python/func_abc.py program itself. 472 473 This shows which function is calling which - the output above ends by 474 showing that func_a called func_b which in turn called func_c etc. 475 476 The TIME(us) column shows time from boot in microseconds. 477 478 The FILE column shows the file that was being executed. 479 480 If the output looks strange, check the CPU "C" column - if it changes, 481 then the output is probably shuffled. See Notes/ALLsnoop_notes.txt for 482 details and suggested workarounds. 483 484 See Notes/ALLflow_notes.txt for important notes about reading flow outputs. 485 486
