<modname>.err files contain a #define statement for each message. For example:
// Error code definitions for module "kernapi/api"
#include "kernutil/errorsys/errorsys.hxx"
#include "error/message/errmsg.hxx"
extern message_module api_errmod;
#define API_FAILED api_errmod.message_code(0)
#define EMPTY_ARRAY api_errmod.message_code(1)
...
#define SMALL_RAD1 api_errmod.message_code(27)
#define SMALL_RAD2 api_errmod.message_code(28)
#define SMALL_LENGTH api_errmod.message_code(29)
...
The e<modname>.cxx file contains the definition of the error module for the messages in this module:
// Error code definitions for module "kernapi/api"
#include "acis.hxx"
#include <stdio.h>
#include "kernutil/errorsys/errorsys.hxx"
#include "error/message/errmsg.hxx"
static message_list api_msglst[] =
{
		{"API_FAILED", "operation unsuccessful"},
		{"EMPTY_ARRAY", "array with no members given"},
...
	{"SMALL_RAD1", "radius 1 is too small"},
		{"SMALL_RAD2", "radius 2 is too small"},
		{"SMALL_LENGTH", "length is too small"},
...
	{NULL, NULL}
};
message_module api_errmod("kernapi/api", api_msglst);
