Process Object

The process object, just like on other OSes is a container of the following resources:

• Handle table
• Memory regions
• Threads

In general it operates more or less like a Linux or Windows process in terms of being it associated with code (one or more ELF binaries) which it is executing until it is forcefully terminated or the program exits.

Lifetime

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().

A thread in another process can wait for a process to exit with sys_process_join().
