pm_stop_thread and pm_tstop_thread Subroutine

Purpose

Stops Performance Monitor counting for a target thread.

Library

Performance Monitor APIs Library (libpmapi.a)

Syntax

#include <pmapi.h> int pm_stop_thread (pid, tid) pid_t pid; tid_t tid; int pm_tstop_thread (pid, tid, *time) pid_t pid; tid_t tid; timebasestruct_t *time;

Description

This subroutine supports only the 1:1 threading model. It has been superseded by the pm_stop_pthread subroutine, which supports both the 1:1 and the M:N threading models. A call to this subroutine is equivalent to a call to the pm_stop_pthread subroutine with a ptid parameter equal to 0.

The pm_stop_thread subroutine stops Performance Monitor counting for a target kernel thread. The thread must be stopped and must be part of a debuggee process, under the control of the calling process.

The pm_tstop_thread subroutine stops Performance Monitor counting for a target kernel thread, and returns a timestamp indicating when the counting was stopped.

Parameters

Item	Description
pid	Process ID of target thread. Target process must be a debuggee of the caller process.
tid	Thread ID of target thread.
*time	Pointer to a structure containing the timebase value when the counting was stopped. This can be converted to time using the time_base_to_time subroutine.

Return Values

Item	Description
0	Operation completed successfully.
Positive error code	Refer to the pm_error Subroutine to decode the error code.

Error Codes

Refer to the pm_error Subroutine.
