31 set_field_buffer() sets buffer buf of field to value. Buffer 0 stores
32 the displayed contents of the field. Buffers other than 0 are applica‐
33 tion specific and not used by the forms library routines. field_buf‐
34 fer() returns the value of field buffer buf.

36
37 Every field has an associated status flag that is set whenever the con‐
38 tents of field buffer 0 changes. set_field_status() sets the status
39 flag of field to status. field_status() returns the status of field.

42 set_max_field() sets a maximum growth on a dynamic field, or if max=0
43 turns off any maximum growth.
