form_page(3X)			  Library calls 		   form_page(3X)

NAME
     form_page - set and get form page number

SYNOPSIS
     #include <form.h>

     int set_current_field(FORM *form, FIELD *field);
     FIELD *current_field(const FORM *form);

     int unfocus_current_field(FORM *form);

     int set_form_page(FORM *form, int n);
     int form_page(const FORM *form);

     int field_index(const FIELD *field);

DESCRIPTION
     The  function  set_current_field  sets the current field of the given form;
     current_field returns the current field of the given form.

     The function unfocus_current_field removes the focus from the current field
     of the form.  In such state, inquiries via  current_field	shall  return  a
     NULL pointer.

     The  function  set_form_page sets the form's page number (goes to page n of
     the form).

     The function form_page returns the form's current page number.

     The function field_index returns the index of the field in the field  array
     of the form it is connected to.  It returns ERR if the argument is the null
     pointer or the field is not connected.

RETURN VALUE
     Except for form_page, each routine returns one of the following:

     E_OK
	  The routine succeeded.

     E_BAD_ARGUMENT
	  Routine detected an incorrect or out-of-range argument.

     E_BAD_STATE
	  Routine was called from an initialization or termination function.

     E_INVALID_FIELD
	  Contents of a field are not valid.

     E_REQUEST_DENIED
	  The form driver could not process the request.

     E_SYSTEM_ERROR
	  System error occurred (see errno(3)).

PORTABILITY
     These routines emulate the System V forms library.  They were not supported
     on Version 7 or BSD versions.

     The unfocus_current_field function is an ncurses extension.
