field_init() function returns a pointer to the
  function that will be called just after the current field changes and just
  before the form is posted, this function may be set by using the
  set_field_init() function. Similarly, the function
  field_term() will return a pointer to the function
  that will be called just before the current field changes and just after the
  form is unposted, this function pointer may be set by using the
  set_field_term() function. The
  form_init() function will return a pointer to the
  function that will be called just before the form is posted to the screen,
  this function can be set by calling the
  set_form_init() function. The
  form_term() function will return a pointer to the
  function that will be called just after the form is unposted from the screen,
  this function may be set by using the set_form_term()
  function. By default, the init and term function pointers are
  NULL.
NULL if an
  error is detected. The functions that return an int will return one of the
  following error values:
E_OK<form.h>
  automatically includes both
  <curses.h> and
  <eti.h>.
