8 * This file defines the error and message codes for the JPEG library.
9 * Edit this file to add new codes, or to translate the message strings to
10 * some other language.
11 * A set of error-reporting macros are defined too. Some applications using
12 * the JPEG library may wish to include this file to get the error codes
13 * and/or the macros.

17 * To define the enum list of message codes, include this file without
18 * defining macro JMESSAGE. To create a message string table, include it
19 * again with a suitable JMESSAGE definition (see jerror.c for an example).
