LIBRARY
     Curses Form Library (libform, -lform)

SYNOPSIS
     #include <form.h>

     int
     field_count(FORM *form);

     FIELD **
     form_fields(FORM *form);

     int
     move_field(FIELD *field, int frow, int fcol);

     int
     set_form_fields(FORM *form, FIELD **fields);

DESCRIPTION
     The field_count() function returns the number of fields that are attached to the given form, if the form argument passed is NULL then
     field_count() will return -1.  The function form_fields() will return a pointer to array of attach fields for the given form, this array is
     not NULL terminated, fields may be attached to the given form by calling set_form_fields().  The fields argument in this function is a
     pointer to a NULL terminated array of fields that will be attached to the form.  If there are already fields attached to the form then they
     will be detached before the new fields are attached.  The new fields given must not be attached to any other form.  The move_field() function
     will move the given field to the location specified by frow and fcol.

RETURN VALUES
     Functions returning pointers will return NULL if an error is detected.  The functions that return an int will return one of the following
     error values:

     E_OK		The function was successful.
     E_CONNECTED	The field is connected to a form.
     E_POSTED		The form is currently posted to the screen.
