Saluton! I am presently using 'Programming Ruby' but I have problems with the over-minimalistic description of the C function's behavior. I did google (both on WWW and Usenet) but that didn't reveal anything useful. I for example need some more detailed information on how REALLOC_N works to avoid core dumps which I presently face :-< The descriptions in 'Programming Ruby' are insufficient for old C hands ...
