Read hardware counters from an event set. More...
PAPI_read() copies the counters of the indicated event set into the provided array.
The counters continue counting after the read.
Note the differences between PAPI_read() and PAPI_accum(), specifically that PAPI_accum() resets the values array to zero.
PAPI_read() assumes an initialized PAPI library and a properly added event set.
