threaded_engine_post/2 — Logtalk 3.100.1

built-in predicate

# `threaded_engine_post/2`

## Description

    threaded_engine_post(Engine, Term)

Posts a term to the engine term queue.

Note

This predicate requires a backend Prolog compiler providing compatible multi-threading primitives. The value of the read-only engines flag is set to `supported` when that is the case.

## Modes and number of proofs

    threaded_engine_post(@nonvar, @term) - one

## Errors

`Engine` is a variable:
`instantiation_error`
`Engine` is neither a variable nor the name of an existing engine:
`existence_error(engine, Engine)`

## Examples

    % post the atom "ready" to the worker_1 engine queue:
    | ?- threaded_engine_post(worker_1, ready).
