Returns Performance Monitor data for the counting group to which the calling thread belongs.
Performance Monitor APIs Library (libpmapi.a)
#include <pmapi.h> int pm_get_data_mygroup (*pmdata) pm_data_t *pmdata; int pm_get_tdata_mygroup (*pmdata, *time) pm_data_t *pmdata; timebasestruct_t *time;
The pm_get_data_mygroup subroutine retrieves the current Performance Monitor data for the group to which the calling kernel thread belongs.
The pm_get_tdata_mygroup subroutine retrieves the current Performance Monitor data for the group to which the calling thread belongs, and a timestamp indicating the last time the hardware counters were read.
The Performance Monitor data is always a set (one per hardware counter on the machine used) of 64-bit values. The information returned also includes the characteristics of the group, such as the number of its members, if it is a process level group, and if its counters are consistent with the sum of the counters for all of the threads in the group.
