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.

    NULL if an error is detected. The functions that
    return an int will return one of the following error values:
