which function? A function within a DLL file. declared how?
Something like: void foo( void *bar)
used how?
MyClass foo: bar ^ self ffiCall: #(void foo( void *bar))
MyClass foo: 0 MyClass foo: FFIExternalObject null
is "ExternalAddress nullâ what you want.

Hi,
I wanted to call a function using null as argument but did not managed
to do so.
I tried to use an integer, but the FFI forbids it.
I tried to use FFIExternalObject null, but the FFI vould not coerce
the arguments.
To make it work I had to duplicate the method and set 0 instead of an
argument.
void foo (0);
Is it possible to do it the first way ?
