That was the general intention, but seems not to cover this example. Howver, #include <R.h> #undef Realloc #define R_Realloc(p,n,t) (t *) R_chk_realloc( (void *)(p), (size_t)((n) * sizeof(t)) ) #include <windows.h> seems to work. > On Thu, 23 Nov 2006, Tom McCallum wrote: > >> Thank you for your reply.
