form_page(3)        UNIX Programmer's Manual         form_page(3)

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 *);
     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 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.

     lowing:
