process - Process abstraction
A zircon process is an instance of a program in the traditional sense: a set of instructions which will be executed by one or more threads, along with a collection of resources.
The process object is a container of the following resources:
In general, it is associated with code which it is executing until it is forcefully terminated or the program exits.
Processes are owned by jobs and allow an application that is composed by more than one process to be treated as a single entity, from the perspective of resource and permission limits, as well as lifetime control.
A process is created via sys_process_create() which take no parameters.
The process starts destruction when main thread terminates or the last handle
is closed. [⚠ not implemented].
Next, the main binary is loaded into the process via sys_process_load() and
its execution begins with sys_process_start().
- process_create - create a new process within a job
- process_read_memory - read from a process's address space
- process_start - cause a new process to start executing
- process_write_memory - write to a process's address space
- process_exit - exit the current process
- job_create - create a new job within a parent job
- vmar_map - Map memory into an address space range
- vmar_protect - Change permissions on an address space range
- vmar_unmap - Unmap memory from an address space range
