Where can I get a library for code to access hardware performance counters from inside a C++ program?

[gostanian__richard]

I know how to access performance counters from tools like perf and pcm, but I would like to associate hardware counters with particular lines of code in my application. Is there a library that implements the PAPI interface or some other way to get at the hardware counters from inside a C++ program?  Where can I download it from?

PAPI the library implements the PAPI interface!

You can find a list of other options here.

There is very nice C++ tool to easily program performance counters from Morgan Stanley Xpedite

This allows programmer to easily instrument a section of code for performance counters.
