6 syserrlst - error message file format
7
9 mkerrlst(1), creates error message files in the format described below.
10
11 An ``error message file'' consists of a header, an array of structures
12 specifying the offset and length of each message, and the array of mes‐
13 sage strings separated by newlines.
14
15 The message strings are separated by newlines but the newline charac‐
16 ters are not included in the size of the message. These newline char‐
17 acters serve only to make the file editable or printable (after strip‐
18 ping off the header).
19
20 The file format is:
21
22 /*
23 * Definitions used by the 'mkerrlst' program which creates error message
24 * files.
25 *
26 * The format of the file created is:
27 *
28 * struct ERRLSTHDR ehdr;
29 * struct ERRLST emsg[num_of_messages];
30 * struct {
31 * char msg[] = "error message string";
32 * char lf = '0;
33 * } [num_of_messages];
34 *
35 * Note: the newlines are NOT included in the message lengths, the newlines
36 * are present to make it easy to 'cat' or 'vi' the file.
