[comp.sys.mac.hypercard] How to build a XCMD with Think C and how does it work?

ltmatthey@cnedcu51.bitnet (06/21/91)

Hello!
I am trying to build XCMD and XFCN ressources for Hypercard with Think C.
I am tried an example from the book "Macintosh Programming PRIMER", Addison-
Wesley Publishing and it runs... But I don't know how it runs exactely. There
is a parameter block which passes from Hypercard to the C routine. Does anyone
can tell me more about this parameter and especially about the structure of
this parameter?

Does anyone have some notes or some references about XCMD and XFCN ressources
building with Think C for Hypercard.

Thank you very much in advance...
