Stops Performance Monitor counting for the 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 It has been superseded by the pm_stop_pgroup subroutine, which supports both the 1:1 and the M:N threading models.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_stop_pgroup subroutine with a ptid parameter equal to 0.
The pm_stop_group subroutine stops Performance Monitor counting for a target kernel thread, the counting group to which it belongs, and all the other thread members of the same group. Counting stops immediately for all the threads in the counting group. The target thread must be stopped and must be part of a debuggee process, under control of the calling process.
The pm_tstop_group subroutine stops Performance Monitor counting for a target kernel thread, the counting group to which it belongs, and all the other thread members of the same group, and returns a timestamp indicating when the counting was stopped.

|---|---|
| pid | Process ID of target thread. Target process must be a debuggee of the caller process. |
| tid | Thread ID of target thread. |
| *time | Pointer to a structure containing the timebase value when the counting was stopped. This can be converted to time using the time_base_to_time subroutine. |
