NAME
       new_form, free_form - create and destroy forms

       #include <form.h>

       FORM *new_form(FIELD **fields);
       int free_form(FORM *form);

DESCRIPTION
       The function new_form creates a new form connected to a specified field
       pointer array (which must be NULL-terminated).

       The function free_form disconnects form from its field array and frees
       the storage allocated for the form.

RETURN VALUE
       The function new_form returns NULL on error.  It sets errno according
       to the function's success:

       E_OK The routine succeeded.

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

       E_CONNECTED
            The field is already connected to a form.

       E_SYSTEM_ERROR
            System error occurred, e.g., malloc failure.

       The function free_form returns one of the following:

       E_OK The routine succeeded.

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

       E_POSTED

       supported on Version 7 or BSD versions.
