NAME

       new_form, free_form - create and destroy forms

SYNOPSIS

       #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
