Purpose

Resets Performance Monitor data for a target pthread.

Library

Performance Monitor APIs Library (libpmapi.a)

Syntax

#include <pmapi.h>

int pm_reset_data_pthread ( pid,  tid,  ptid)
pid_t pid;
tid_t tid;
ptid_t ptid;

Description

The pm_reset_data_pthread subroutine resets the current Performance Monitor data for a target pthread. The pthread must be stopped and must be part of a debuggee process. The data is a set (one per hardware counter on the machine used) of 64-bit values. All values are reset to 0.

If the pthread is running in 1:1 mode, only the tid parameter must be specified. If the pthread is running in m:n mode, only the ptid parameter must be specified. If both the ptid and tid parameters are specified, they must be referring to a single pthread with the ptid parameter specified and currently running on a kernel thread with specified tid parameter.

Parameters

pid Process ID of target pthread. Target process must be a debuggee of the caller process.
tid Thread ID of target pthread. To ignore this parameter, set it to 0.
ptid Pthread ID of the target pthread. To ignore this parameter, set it to 0.
