calling XSUBs from other XSUBs?

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

How do you call an XSUB from another XSUB? is perl_call_* the best way to do it, or is there some method of calling it directly, perhaps after placing the arguments on the stack?

After a few websearches, it seems as if you can use: `(void)(*CvXSUB(cv))(cv);` [download] to skip the overhead of perl_call_sv() and call the internal C code directly. Supposedly, this is much faster. I've only barely touched perlguts, perlapi, anc perlcall stuff with C modules, so I'm unsure, but I hope it works for you. At least it might get you started. --jb	[reply] [d/l]
