Retrieves systemwide Performance Monitor settings.
Performance Monitor APIs Library (libpmapi.a)
#include <pmapi.h>
int pm_get_program ( *prog)
pm_prog_t *prog;
The pm_get_program subroutine retrieves the current systemwide Performance Monitor settings. 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 user mode, the kernel mode, the current counting state, and the process tree mode. If the process tree mode is on, the counting applies only to the calling process and its decendants.
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.
If the events are represented by a group ID, then the is_group bit is set in the mode, and the first element of the events array contains the group ID. The other elements of the events array are not meaningful.
