NAME

6       utrace_control_pid - control a thread being traced by a tracing engine
7

SYNOPSIS

9       __must_check int utrace_control_pid(struct pid * pid,
10                                           struct utrace_engine * engine,
11                                           enum utrace_resume_action action);
12

ARGUMENTS

14       pid
15           thread to affect
16
17       engine
18           attached engine to affect
19
20       action
21
22           enum utrace_resume_action for thread to do
23

DESCRIPTION

25       This is the same as utrace_control, but takes a struct pid pointer
26       rather than a struct task_struct pointer. The caller must hold a ref on
27       pid, but does not need to worry about the task staying valid. If it´s
28       been reaped so that pid points nowhere, then this call returns -ESRCH.
