\fBform_field_buffer\fR - field buffer control
The function \fBset_field_buffer\fR 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 \fBnbuf\fR
-argument of (see \fBfield_new\fR(3X)) but are not manipulated by the forms
-library. The function \fBfield_buffer\fR returns the foreground attribute.

+library. The function \fBfield_buffer\fR 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 trailing 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.

is set to a nonzero value whenever the field changes.
The function \fBset_max_field\fR sets the maximum size for a dynamic field.
