Description

An error code. Error codes are often numeric, but in some environments they may be symbolic constants.

DocBook provides four elements for identifying the parts of an error message: errorcode, for the alphanumeric error code (e.g., “–2”); errorname, for the symbolic name of the error (e.g., “ENOENT”); errortext, for the text of the error message (e.g., “file not found”); and errortype, for the error type (e.g., “recoverable”).

Not Found</errortext> error by returning
<errorcode>2</errorcode> (<errorname>ENOENT</errorname>).  This is usually a
<errortype>recoverable</errortype> (nonfatal) error.
