-<H2>DESCRIPTION</H2><PRE>
- The function <STRONG>set_field_buffer</STRONG> sets the numbered buffer of
- the given field to contain a given string. Buffer 0 is
- the displayed value of the field; other numbered buffers
- may be allocated by applications through the <STRONG>nbuf</STRONG> argument
- of (see <STRONG><A HREF="form_field_new.3x.html">form_field_new(3x)</A></STRONG>) but are not manipulated by the
- forms library. The function <STRONG>field_buffer</STRONG> returns the
- address of the buffer. Please note that this buffer has
- always the length of the buffer, that means that it may
- typically contain trailing spaces. If you entered leading
- spaces the buffer may also contain them. If you want the
- raw data, you must write your own routine that copies the
- value out of the buffer and removes the leading and trail-
- ing spaces. Please note also, that subsequent operations
- on the form will probably change the content of the
- buffer. So don't use it for long term storage of the
- entered form data.
-
- The function <STRONG>set_field_status</STRONG> sets the associated status
- flag of <EM>field</EM>; <STRONG>field_status</STRONG> gets the current value. The
- status flag is set to a nonzero value whenever the field
- changes.
-
- The function <STRONG>set_max_field</STRONG> sets the maximum size for a
- dynamic field. An argument of 0 turns off any maximum
- size threshold for that field.
