NTSTATUSstyle

NTSTATUSstyle is a naming convention used for Windows NT status codes. These codes are returned by system functions to indicate the success or failure of an operation. The naming convention follows a specific pattern that helps developers understand the nature of the returned status.

The typical format of an NTSTATUS code is `STATUS_SYMBOLIC_NAME`. The `STATUS_` prefix is a constant identifier for all status codes. The `SYMBOLIC_NAME` part is descriptive, often indicating the component or subsystem that returned the code, and a brief description of the outcome. For example, `STATUS_SUCCESS` indicates that an operation completed without any issues. `STATUS_ACCESS_DENIED` signifies that the caller lacked the necessary permissions to perform the requested action. `STATUS_INVALID_PARAMETER` means that one or more arguments passed to the function were invalid.

Understanding NTSTATUSstyle is crucial for Windows kernel development and driver programming. It allows developers to reliably check the results of system calls and implement appropriate error handling logic. While many NTSTATUS codes are documented, some are reserved for internal use or specific driver implementations. The interpretation of these codes helps in diagnosing issues and ensuring the stability of Windows-based systems.
