+ * NOTE: The CGIs in this file use parameter names

+ * However, I'm trying to save bytes in the

- * Therefore if you are going to keep the string for

- * strdup() it and free() the original, to save memory.
- *
- *
- * Parameters :
- * 1 : dest = destination for newly malloc'd pointer to
- * line data. Will be set to NULL on error.
- * 2 : fp = File to read from
- *
- * Returns : JB_ERR_OK on success

- *
- * Function : edit_read_line
- *
- * Description : Read a single non-empty line from a file and return
- * it. Trims comments, leading and trailing whitespace
- * and respects escaping of newline and comment char.
- * Provides the line in 2 alternative forms: raw and
- * preprocessed.
- * - raw is the raw data read from the file. If the
- * line is not modified, then this should be written
- * to the new file.
- * - prefix is any comments and blank lines that were
- * read from the file. If the line is modified, then
- * this should be written out to the file followed
- * by the modified data. (If this string is non-empty
- * then it will have a newline at the end).
- * - data is the actual data that will be parsed
- * further by appropriate routines.
- * On EOF, the 3 strings will all be set to NULL and
- * 0 will be returned.
- *
- * Parameters :
- * 1 : fp = File to read from
- * 2 : raw_out = destination for newly malloc'd pointer to
- * raw line data. May be NULL if you don't want it.
- * 3 : prefix_out = destination for newly malloc'd pointer to
- * comments. May be NULL if you don't want it.
- * 4 : data_out = destination for newly malloc'd pointer to
- * line data with comments and leading/trailing spaces
- * removed, and line continuation performed. May be
- * NULL if you don't want it.

- * Returns : JB_ERR_OK on success

*
- * Netscape 4's JavaScript sucks - it doesn't use
- * "id" parameters, so you have to set the "name"
- * used to submit a form element to something JavaScript
- * will like. (Or access the elements by index in an

- * be changed whenever we add a new action to the
- * editor, so I'm NOT going to use indexes that have
- * to be figured out by hand.)
+ * Parameters :
+ * 1 : csp = Current client state (buffers, headers, etc...)
+ * 2 : rsp = http_response data structure for output
+ * 3 : file = The file that was modified.
*
- * Currently the only thing we have to worry about
- * is "-" ==> "_" conversion.
- *
- * This is a length-preserving operation so it is
- * carried out in-place, no memory is allocated
- * or freed.
- *
- * Parameters :
- * 1 : identifier = String to make JavaScript-friendly.

- * Returns : N/A
