Retrieves the Performance Monitor settings for the counting group to which a target thread belongs.
Performance Monitor APIs Library (libpmapi.a)
This subroutine supports only the 1:1 threading model. It has been superseded by the pm_get_program_pgroup subroutine, which supports both the 1:1 and the M:N threading models. A call to this subroutine is equivalent to a call to the pm_get_program_pgroup subroutine with a ptid parameter equal to 0.
The pm_get_program_group subroutine retrieves the Performance Monitor settings 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. This includes mode information and the events being counted, which are in a list of event identifiers. The identifiers come from the lists returned by the pm_init subroutine.
The counting mode includes the user mode and kernel mode, and the current counting state.
If the list includes an event which can be used with a threshold (as indicated by the pm_init subroutine), a threshold value is also returned.
