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

Need Help??

NERDVANA has asked for the wisdom of the Perl Monks concerning the following question:

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'?

FWIW: My idea was that a direct call is more efficient. Hence the XS equivalent to `$sub = UNIVERSAL::can($obj, "print");` But `UNIVERSAL` says > # but never do this! Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]
