Hi Brad !
- The Performer C-API generator produced pfNewShadow wrong. I fixed it for
the 3.0 release.
- The prototype of the call pfShadowAddChannel is
pfShadowAddChannel(pfShadow* _shadow, pfChannel *channel);
The man page is also correct. Where exactly did you find the example below ?
If you want, you can send me your C example. I can compile and run it against
my C-API fix (just to verify that it really fixes your problem).
Thanks,
-yair
