int

# 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_CONNECTED`
  The field is connected to a form.
`E_POSTED`
