Im looking to check the relative time it takes to call a function and then return. does anyone know how i can do this easily? heres what im hoping i can do... int len; len = check_timer(); function_to_time(); len = check_timer() - len; and have this return some number telling me the relative time to execute the function. if this isnt clear let me know and ill clarify. thank you in advance!
