Returns Performance Monitor data for the counting group to which a target thread belongs.

pm_data_t *pmdata;
The pm_get_data_group subroutine retrieves the current Performance Monitor data for the counting group to which a target kernel thread belongs. The thread must be stopped and must be part of a debuggee process under the control of the calling process. The data is 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.
