field_buffer() function returns the contents of the
  buffer number specified by buffer for the given field.
  If the requested buffer number exceeds the number of buffers attached to the
  field then NULL will be returned. If the field option
  O_REFORMAT is enabled on the given field then storage
  will be allocated to hold the reformatted buffer. This storage must be release
  by calling free(3) when it is no
  longer required. If the O_REFORMAT field option is not
  set then no extra storage is allocated. The field buffer may be set by calling
  set_field_buffer() which will set the given buffer
  number to the contents of the string passed. A buffer may also be set by
  calling set_field_printf() which sets the buffer using
  the format arg fmt after being expanded using the
  subsequent arguments in the same manner as
  sprintf(3) does. Calling
  field_status() will return the status of the first
  buffer attached to the field. If the field has been modified then the function
  will return TRUE otherwise
  FALSE is returned, the status of the first buffer may
  be programmatically set by calling set_field_status().
  The maximum growth of a dynamic field can be set by calling
  set_max_field() which limits the fields rows if the
  field is a multiline field or the fields columns if the field only has a
  single row.
NULL if an
  error is detected. The functions that return an int will return one of the
  following error values:
E_OKE_BAD_ARGUMENTE_SYSTEM_ERROR<form.h>
  automatically includes both
  <curses.h> and
  <eti.h>. The function
  set_field_printf() is a NetBSD
  extension and must not be used in portable code.
