Detailed Description

Unified kernel error type.

Note

Combines an error category with a subsystem-specific code. Use the from_* factory methods for type-safe construction.

Constructor & Destructor Documentation

kernel_error()

inlineconstexprexportnoexcept

Construct from category and raw code.

Parameters

[in]	cat	Error category.
