Yes, quite. > The approach I had in mind was to build an XS file full of Perl <-> C thunks > and then use the closure-over-dlfunc-pointer trick of P5NCI to avoid writing > (and paying the cost of) hundreds of otherwise-identical XS wrappers. Ah, well, I had perhaps an incomplete understanding of the problem. I thought we needed to create complex data structures for some newer OpenGL calls, so I wanted to ease the difficulty of making complex C data structures from Perl. If, OTOH, the primary problem is exposing a very broad API from C to Perl, then yes, reusing XS wrappers is very good (reduced memory use, better cache coherency, blah blah). > This is > even one spot where a little AUTOLOAD magic would help memory usage even more. > > -- c
