current_field
() returns a pointer to the structure
for the field that is currently active on the page. If there is an error,
current_field
() will return
NULL
. Calling field_index
()
will return the index of the given field in the form field array. The current
page the form is on can be determined by using
form_page
(), the current page of a form can be
programmatically set by calling set_form_page
(). The
maximum page number for a form can be found by calling the function
form_max_page
() but note that this function is a
NetBSD extension and must not be used in portable
forms library programs. The current field on the form may be set by calling
set_current_field
() which will set the current field
to the one given.
NULL
if an
error is detected. The functions that return an int will return one of the
following error values:
E_OK
E_BAD_ARGUMENT
E_NOT_CONNECTED
E_BAD_STATE
E_INVALID_FIELD
<form.h>
automatically includes both

The form_max_page

NetBSD extension and should not be used in portable
applications.
