Detailed Description¶
Abstract base class for types defining a category of error codes.
An error category defines a context that give meaning to the integer stored in an error_code or error_condition object. For example, the standard errno constants such a EINVAL and ENOMEM are associated with the 'generic' category and other OS-specific error numbers are associated with the 'system' category, but a user-defined category might give different meanings to the same numerical values.
