Unfortunatly, I don't think type input/output functions can be written in anything other than C. IIRC, no other PL understands the cstring type. As for why, well, because nobody has done the legwork yet. Oh yes, type input/output functions are also called at various points, including during parsing where there is no current snapshot. Whether the PLs are affected by this I don't know, but you cannot do SPI at that point. Hope this helps, -- Martijn van Oosterhout <kleptog@xxxxxxxxx> http://svana.org/kleptog/ > Patent. n.
