Status codes

Overview

Status codes are numeric values that represent unique conditions. Each code also has a mnemonic such as E_OK, which indicates successful completion or E_MEM which indicates not enough memory.

When you write source code you can refer to status codes by their mnemonics. The RT kernel includes files that contain literal declarations for RT status codes.

Status code values fall into ranges based on the RT layer that first detects the condition and the type of exception. This shows the ranges based on the error type and the layer that detects the condition. Numeric values appear in hexadecimal.

Numeric processor extension exceptions: 0x8007 (NPX error)
All other programming and environmental exceptions:

Source	Environmental conditions	Programming errors
RT kernel	`0x0` to `0x3FFF`	`0x8000` to `0xBFFF`

Status values (high-level calls)

All of the status code values which can be returned by the kernel are listed here.
