Accesses an integer.
SP_get_float()
Accesses a float.
SP_get_atom()
Accesses an atom.
SP_get_string()
Accesses an atom.
SP_get_address()
Accesses an integer representing a pointer.
SP_get_list_codes()
Accesses a code-list.
SP_get_list_n_codes()
Accesses a code-list.
SP_get_number_codes()
Accesses a code-list denoting a number.
SP_get_integer_bytes()
Accesses an arbitrarily sized integer.
SP_get_functor()
Accesses a compound term.
SP_get_list()
Accesses a list.
