#include <sicstus/sicstus.h> int SP_get_list_codes(SP_term_ref term, char const **s);
*s a zero-terminated array containing an encoded
string that corresponds to the given Prolog code-list. The array
is subject to reuse by other support functions, so if the value is going
to be used on a more than temporary basis, it must be moved elsewhere.
Zero if the conversion fails (as far as failure can be detected), and a nonzero value otherwise.
