- * SYNOPSIS
- * RB_Analyse_Xrefs (xreffiles_file)
- * RB_Analyse_Xrefs (FILE *)
- * FUNCTION
- * Scan the file xreffiles_file. This file contains the
- * names of one or more xref files. All the references in the
- * files are scaned and stored in a link list of the type
- * RB_link. These xref files can be generated with robodoc.
- * INPUTS
- * xreffiles_file - a file pointer to the file with xref file
- * names.
- * RESULT
- * none
- * BUGS
- * Might fail if there are syntax errors in one of the xref
- * files.
- * Bad use of feof() and fgets().

- * Searches for the given word in the list of links and

- * In the second pass it is any string that consists of alpha
- * numerics, '_', ':', '.', or '-'.
- * In the third pass (for C) it is any string that consists
- * of alpha numerics or '_'.
- * In the last pass it is any string that consists of alpha
- * numerics.
- * INPUTS
- * word_begin - pointer to a word (a string).
- * label_name - pointer to a pointer to a string
- * file_name - pointer to a pointer to a string
- * SIDE EFFECTS
- * label_name & file_name are modified
