Struct procfs::process::Task

pub struct Task {
    pub pid: i32,
    pub tid: i32,
    /* private fields */
}

A task (aka Thread) inside of a Process

Created by Process::tasks, tasks in general are similar to Processes and should have mostly the same fields.

Fields

pid: i32

The ID of the process that this task belongs to

tid: i32

The task ID

Implementations

impl Task

pub fn stat(&self) -> ProcResult<Stat>

Thread info from /proc/<pid>/task/<tid>/stat

Many of the returned fields will be the same as the parent process, but some fields like utime and stime will be per-task

pub fn status(&self) -> ProcResult<Status>

Thread info from /proc/<pid>/task/<tid>/status

Many of the returned fields will be the same as the parent process

pub fn io(&self) -> ProcResult<Io>

Thread IO info from /proc/<pid>/task/<tid>/io

This data will be unique per task.

pub fn schedstat(&self) -> ProcResult<Schedstat>

Thread scheduler info from /proc/<pid>/task/<tid>/schedstat

This data will be unique per task.

pub fn children(&self) -> ProcResult<Vec<u32>>

Thread children from /proc/<pid>/task/<tid>/children

WARNING: This interface is not reliable unless all the child processes are stoppped or frozen. If a child task exits while the file is being read, non-exiting children may be omitted. See the procfs(5) man page for more information.

This data will be unique per task.

pub fn read<T: FromRead>(&self, path: &str) -> ProcResult<T>

Parse a file relative to the task proc structure.
