NAME
       syserrlst - error message file format

DESCRIPTION
       mkerrlst(1), creates error message files in the format described below.

       An  ``error  message file'' consists of a header, an array of structures specifying the offset and length of each message, and the array of
       message strings separated by newlines.

       The message strings are separated by newlines but the newline characters are not included in the size of the message.  These newline  char-
       acters serve only to make the file editable or printable (after stripping off the header).

       The file format is:

       /*
	* Definitions used by the 'mkerrlst' program which creates error message
	* files.
	*
	* The format of the file created is:
	*
	*   struct    ERRLSTHDR ehdr;
	*   struct    ERRLST  emsg[num_of_messages];
	*   struct    {
	*	 char msg[] = "error message string";
	*	 char lf = '0;
	*	 } [num_of_messages];
	*
	* Note:  the newlines are NOT included in the message lengths, the newlines
	*	 are present to make it easy to 'cat' or 'vi' the file.
       */

		 short	   magic;
		 short	   maxmsgnum;
		 short	   maxmsglen;
		 short	   pad[5];	  /* Reserved */
		 };

	    struct    ERRLST
		 {
		 off_t	   offmsg;
		 short	   lenmsg;
		 };
