Operating systems are built on a kernel that provides fundamental functions for applications to interact with hardware and manage system resources. These functions include:

Memory Management: Allocating and managing memory for processes.
File System Management: Reading, writing, and organizing files.
Process Management: Creating, scheduling, and terminating processes.
Device Management: Communicating with hardware devices through drivers.
Networking: Handling network communications.

When an application calls one of these functions and it fails, the OS reports an error, often manifesting as “a call to an OS function failed beyond compare.”

6.2 System Calls

A system call is a request from an application to the operating system’s kernel. It’s the primary way applications interact with the OS. When a system call fails, it can be due to:

Invalid Parameters: The application passed incorrect or invalid parameters to the system call.
Resource Constraints: The system doesn’t have enough resources to fulfill the request.
Permissions Issues: The application doesn’t have the necessary permissions to perform the requested operation.
Hardware Failures: The underlying hardware is malfunctioning.

6.3 Error Codes

When a system call fails, the OS returns an error code to indicate the reason for the failure. These error codes are typically numeric values that correspond to specific error conditions. Common error codes include:

ERROR_ACCESS_DENIED: The application doesn’t have permission to access the requested resource.
ERROR_INVALID_HANDLE: The handle passed to the system call is invalid.
ERROR_NOT_ENOUGH_MEMORY: The system doesn’t have enough memory to fulfill the request.
ERROR_FILE_NOT_FOUND: The specified file could not be found.
ERROR_DEVICE_NOT_READY: The device is not ready to perform the requested operation.

6.4 Kernel Mode vs. User Mode

Operating systems typically operate in two modes: kernel mode and user mode.

Kernel Mode: This is the privileged mode where the OS kernel runs. It has unrestricted access to system resources and hardware.
User Mode: This is the restricted mode where applications run. They can only access system resources through system calls.

When an OS function fails, it can occur in either kernel mode or user mode, but kernel mode failures are generally more serious, as they can lead to system-wide instability.
