UTRACE_CONTROL_PID(9) utrace core API UTRACE_CONTROL_PID(9)NAMEutrace_control_pid - control a thread being traced by a tracing engine
SYNOPSIS
__must_check int utrace_control_pid(struct pid * pid,
struct utrace_engine * engine,
enum utrace_resume_action action);
ARGUMENTS
pid

engine
attached engine to affect

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