Returns Performance Monitor data for the counting group to which a target thread belongs.
Performance Monitor APIs Library (libpmapi.a)
int pm_get_data_group ( pid, tid, *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.
|pid||Process identifier of a target thread. The target process must be an argument of a debug process.|
|tid||Thread identifier of a target thread.|
|*pmdata||Pointer to a structure to return the Performance Monitor data for the group to which the target thread belongs.|
|0||No errors occurred.|
|Positive error code||Refer to the pm_error (pm_error Subroutine) subroutine to decode the error code.|
Refer to the pm_error (pm_error Subroutine) subroutine.
|/usr/include/pmapi.h||Defines standard macros, data types, and subroutines.|
