Sets Performance Monitor programmation for the calling thread and creates a counting group.
Performance Monitor APIs Library (libpmapi.a)
#include <pmapi.h>
int pm_set_program_mygroup ( *prog)
pm_prog_t *prog;
The pm_set_program_mygroup subroutine sets the Performance Monitor programmation for the calling kernel thread. The setting includes the events to be counted and a mode in which to count. The events to count are in a list of event identifiers. The identifiers must be selected from the lists returned by the pm_init subroutine.
This call also creates a counting group, which includes the calling thread and any thread which it, or any of its descendants, will create in the future. Optionally, the group can be defined as also containing all the existing and future threads belonging to the calling process.
The counting mode includes User Mode and/or Kernel Mode, and the Initial Counting State. The defaults are set to Off for User Mode and Kernel Mode, and the inital default state is set to delay counting until the pm_start_mygroup subroutine is called.
If the list includes an event which can be used with a threshold (as indicated by the pm_init subroutine), a threshold value can also be specified.
