[Chicken-users] Passing C pointers into C++ code

[Joel Reymont]

Folks,

I'm trying to pass a C pointer into a C++ function. This is what I get:

(setTarget graphics (slot-ref screen 'swig-this))

Error: (class-of) can not compute class of primitive object: #<SWIG-
pointer 163c4a0>

What does this mean?

I set a breakpoint in the debugger on the setTarget wrapper (this is SWIG
code) but the error pops up even BEFORE I get to the wrapper.

Is this a Chicken or a SWIG error?

    Thanks, Joel
