blob_released(@Term)True if Term is a blob whose data was released using
PL_free_blob().
Such a blob still exists as a term and keeps its type, but the object it
referred to is gone: it writes as
<>(freed)
and every predicate that expects the real thing rejects it. Note that
only blobs can be released; an ordinary atom is reclaimed as a whole by
the atom garbage collector and remains valid for as long as it exists.
- Introduced in 10.1.13 (👉a0e29da) blob_released/1 and a safe representation for released blobs
