job - Control a group of processes
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. All the jobs on a Fuchsia system form a tree, with every job, except the root job, belonging to a single (parent) job.
A job is an object consisting of the following:
Jobs allow “applications” that are composed of more than one process to be controlled as a single entity.
zx_job_create()- create a new child job.
zx_job_set_critical()- set a process as critical to a job.
zx_job_set_policy()- set policy for new processes in the job.
zx_process_create()- create a new process within a job.
zx_task_create_exception_channel()- listen for task exceptions
zx_task_kill()- cause a task to stop running.
