6.4.3 Creating Prolog Terms

The following functions create a term and store it as the value of an SP_term_ref, which must exist prior to the call. They return zero if the conversion fails (as far as failure can be detected), and a nonzero value otherwise, assigning to t the converted value.

SP_put_variable()

Creates a variable.

SP_put_integer()

Creates an integer.

SP_put_float()

Creates a float.

SP_put_atom()

Creates an atom.

SP_put_string()

Creates an atom.

SP_put_address()

Creates an integer representing a pointer.

SP_put_list_codes()

Creates a char-list.

SP_put_list_n_codes()

Creates a char-list.

SP_put_list_n_bytes()

Creates a byte-list.

SP_put_integer_bytes()

Creates an arbitrarily sized integer.

SP_put_number_codes()

Creates a char-list denoting a number.

SP_put_functor()

Creates a compound term.

SP_put_list()

Creates a list.

SP_cons_functor()

Creates a compound term with arguments filled in.

SP_cons_list()

Creates a list with arguments filled in.

SP_read_from_string() (C function)

Reads a term from its textual representation, replacing variables by specified terms.
