Detailed Description

OS definitions and system call interfaces for the BEEP-8 system.

This file contains the definitions and system call interfaces for the BEEP-8 operating system. It includes type definitions, constants for scheduling policies and clock IDs, system call enumerations, error codes, and function prototypes for system operations.

Typically, users do not need to use this file directly. It is primarily used by the BEEP-8 bootloader to manage OS-level functionalities such as process and semaphore handling, scheduling, and time management.
