[su.macintosh] Need help with XCMD's and THINK C 4.0

dmr@csli.Stanford.EDU (Daniel M. Rosenberg) (10/12/90)

Help!

We're trying to implement an XCMD in THINK C 4.0, and have followed
the examples from the "How to build XCMD's in HyperCard book" as
closely as possible.

It compiles and runs fine (thanks to getting the XCMD glue stuff direct
from Symantec) but when it runs and does some file i/o and grabbing
memory through NewHandle (and yes, we locked the handles down) the screen
fills with green crud and the machine crashes. The XCMD code runs fine
as a standalone program.

Does anyone have any hints, or, better yet, example code in Think C 4.0?

We're stuck, frustrated, and desperate!

Thanks for any help you can provide --
