Hi,
I'm using R_MakeExternalPtr() to store handles to (COM) objects in a SEXP.
The code basically is
sexp = R_MakeExternalPtr(handle,R_NilValue,R_NilValue);
R_RegisterCFinalizerEx(...);
After creating the sexp, LENGTH(sexp) returns some quite large integer
value. It seems like an "unitialized" value.
Can I safely assume, that an SEXP of type EXTPTRSXP can only contain a
single pointer value and never represent a vector (an array) of pointers? Or
should I maybe explicitly add something like
SETLENGTH(sexp,1);
Best wishes from sunny Austria,
Thomas Baier
