/**** error-file.h --- Error file parsing routines.
 *
 ** Author: Steve Folkes <smf@hermes.mod.uk>
 *
 **** Commentary:
 *
 ***=== INTRODUCTION =========================================================
 *
 * This file specifies the interface to an error description file parsing
 * facility.  This facility extends the error reporting facility specified in
 * the file "error.h" so that error messages may be redefined by the contents
 * of a file.
 *
 ***=== FUNCTIONS ============================================================
 *
 *
 ** Function:   void                    error_file_parse
 *                      PROTO_S ((CStringP name, BoolT must_open))
 ** Exceptions: XX_dalloc_no_memory, XX_ostream_write_error
 *
 * This function parses the error file with the specified name.  If must_open
 * is true, then an error will be reported if the file cannot be opened.
 * Otherwise, the function will just return silently.
 *
 * The format of the file is a sequence of sections.  Sections may appear in
 * any order, and may be repeated.  There are three section types: '%prefix%',
 * '%errors%', and '%strings%'.  The prefix section contains a single string,
 * which is to be used as the error message prefix.  The error and string
 * sections contain a sequence of name and string pairs, where the name names
 * the error or string being redefined, and the string specifies the new
 * contents.  A name is a sequence of characters contained in single quotes,
 * and a string is a sequence of characters contained in double quotes.  In
 * both, the backslash character can be used to escape characters in a similar
 * manner to C.  An example follows:
 *
 *      %prefix% "new error prefix"
 *      %error%
 *              'error message 1' "new error message 1 message"
 *      %string%
 *              'string 1' "new string 1 text"
 *
 * In addition, the '#' character can be used as a comment to end of line
 * character.  Such comments are ignored.
 *
 **** Change log:
 * $Log: error-file.h,v $
 * Revision 1.1.1.1  1998/01/17  15:57:17  release
 * First version to be checked into rolling release.
 *

 * Performing changes for 'CR94_178.sid+tld-update' - bringing in line with
 * OSSG C Coding Standards.
