| # Job |
| |
| ## NAME |
| |
| job - Control a group of processes |
| |
| ## SYNOPSIS |
| |
| A job is a group of processes and possibly other (child) jobs. Jobs are used to |
| track privileges to perform kernel operations (i.e., make various syscalls, |
| with various options), and track and limit basic resource (e.g., memory, CPU) |
| consumption. Every process belongs to a single job. Jobs can also be nested, |
| and every job except the root job also belongs to a single (parent) job. |
| |
| ## DESCRIPTION |
| |
| A job is an object consisting of the following: |
| + a reference to a parent job |
| + a set of child jobs (each of whom has this job as parent) |
| + a set of member [processes](process.md) |
| + a set of policies [⚠ not implemented] |
| |
| Jobs control "applications" that are composed of more than one process to be |
| controlled as a single entity. |
| |
