multithreading - c++ thread running time -

-

i want know whether can calculate running time each thread. implement multithread program in c++ using pthread. know, each thread compete cpu. can use clock() function calculate actual number of cpu clocks each thread consumes?

my program looks like:

class thread () { start(); run(); computing(); };

start() start multiple threads. each thread run computing function something. question how can calculate running time of each thread computing function

no, cannot use clock. processor switch thread between start , computing calls calculate time of several threads. need use tick counter local 1 thread.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
