Had been looking into Luke Tierney's R_AllocatePtr() and was left with a question about exactly when does R reclaim heap memory. Implication of 'simpleref.nw' is that one can allocate C data on the R heap, and as long as pointer object is alive, the data and pointer will remain valid. But it calls allocString() which is implemented using R_alloc().
'Writing R Extensions" says R will reclaim memory allocated using R_alloc() at the end of the .Call(). Was the intent that its invocation be restricted to within a .Call()? Doesn't sound as though it could be used to return an SEXP from a .Call() with its data intact. ---------------------------------------------------------- SIGSIG -- signature too long (core dumped) ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
