Sets system wide Performance Monitor programmation.
Performance Monitor APIs Library (libpmapi.a)
#include <pmapi.h>
int pm_set_program ( *prog)
pm_prog_t *prog;
The pm_set_program subroutine sets system wide Performance Monitor programmation. 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.
The counting mode includes User Mode and/or Kernel Mode, the Initial Counting State, and the Process Tree Mode. The Process Tree Mode sets counting to On only for the calling process and its descendants. The defaults are set to Off for User Mode and Kernel Mode. The initial default state is set to delay counting until the pm_start subroutine is called, and to count the activity of all the processes running in the system.
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.
On some platforms, event groups can be specified instead of individual events. This is done by setting the bitfield is_group in the mode, and placing the group ID into the first element of the events array. (The group ID was obtained by pm_init).
