Is there a Perl API (XS) for ->can ?

[NERDVANA]

Hi, in one of my XS modules I want to do the equivalent of PKG->can($method). It feels like this would be in the perl api, but keyword searching for 'can' is somewhat futile. Is there any way to run this operation more efficiently than literally building a call to method 'can'?

Thanks! gv_fetchmeth was what I was looking for.

FWIW: My idea was that a direct call is more efficient.

Hence the XS equivalent to

$sub = UNIVERSAL::can($obj, "print");

But UNIVERSAL says
