term_to_bytes(?Term, -String)

String is a ground encoding of Term, suitable for writing to a file, transmitting over a network etc.
Prolog term.
A variable.


This predicate produces a string which contains an encoded representation of the term Term. This representation is machine-independent, can be stored in files, sent over networks etc. Note however that the string can contain arbitrary bytes, including NUL and control characters.

The predicate attempts to convert the term with all its attached variable attributes and delayed goals. If this is not wanted, you can strip those by first copying the term using copy_term/2 or copy_term/3.

The term_to_bytes/bytes_to_term predicates differ from term_string/2 in that they do not create a human-readable representation, but are significantly faster and convert the term with all its attributes.

Modes and Determinism


This predicate is sensitive to its module context (tool predicate, see @/2).


(5) type error
String is neither variable nor string.
