digitalmars.D.learn - Measuring ticks (or time) per threads

Hi guys,

I'd like to know if there is a way using the stdlib that I can 
measure the number of ticks that a thread has been working. I do 
mean the number of ticks that it has been ACTIVE, and not the 
noTicks since its creation.

Thanks!

The D core.thread lib could certainly have more functions added 
to it.

If you are using a posix compatible OS, check out

core.sys.posix.sys.resource;

Use this function to get runtime stats
int getrusage(int, rusage*);

For usage details, consult the manpage
http://linux.die.net/man/2/getrusage

The times returned are in seconds+msec but you can convert to 
approx ticks using conversion functions in core.clock.

As for Windows, I have no idea how to get this information, but 
there's probably a way.

That function sounds great. Unfortunately I am working on Windows 
so I guess I'll have to look into their API. I was hoping for a 
solution available in the std but if there isn't than there 
isn't. Thanks for you information!

You may find something in core.sys.windows.windows.d. My 
understanding is that it's not a full interface into the windows 
API, but enough may be there.
