Purpose

Retrieves the Performance Monitor settings for the calling thread.

Library

Performance Monitor APIs Library (libpmapi.a)

Syntax


#include <pmapi.h>


int pm_get_program_mythread ( *prog)
pm_prog_t *prog;

Description

The pm_get_program_mythread subroutine retrieves the Performance Monitor settings for the calling kernel thread. 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 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.

Parameters


*prog Returns which Performance Monitor events and modes are set. Supported modes are:

PM_USER
Counting processes running in user mode

PM_KERNEL
Counting processes running in kernel mode

PM_COUNT
Counting is on

Return Values


0 No errors occurred.
Positive error code Refer to the pm_error (pm_error Subroutine) subroutine to decode the error code.
