I would recommend you first try to create a complete reproducible
example (the code below is just a snippet). Then try to minimize it -
make it do as litt

If your goal is to perform multithreaded computations, why not perform
all necessary interactions with R upfront and then compute only on
primitives? It would help for us to understand your use case.

Your definition can allocate because STING_ELT can allocate.
getAttrib can GC in general. Currently it would not GC or allocate in
thi
Note that your desire is by definition impossible - as your example also shows
checking for S4 inheritance involves evaluation and thus allocation which
cannot be avoided by the dynamic design of S4 inheritance.

AFAIR getAttrib() can allocate as well. Also, R API functions that do
not allocate today, may allocate in the future.

Thank you Luke.
That is why I don't use Rf_inherits but INHERITS which does not
allocate, provided in the email body.
I cannot do similarly for S4 classes, thus asking for some API for that.

Dear R developers,
Motivated by discussion about checking inheritance of S3 and S4
objects (in head matrix/array topic) I would light to shed some light
on a minor gap about that matter in R C API.
Currently we are able to check inheritance for S3 class objects from C
in a robust way (no allocatio
