The thing is, anything in glibconfig.h is _platform specific_. On _your platform_, the macros are defined that way, so GPOINTER_TO_UINT(NULL) is obviously zero. What I was asking was if there were any platforms for which the macro had some weird definition that broke this. > but why would you need to make such an assumption? I'm storing a ref count as the value in a hash table. Since looking up a key in the hash table returns NULL if the key isn't found, it's basically impossible to store a NULL value. It makes life a lot simpler if that corresponds to a ref count of 0, which I don't need to store. > [EMAIL PROTECTED] wrote: > > > Is it possible to assume that > > > > GPOINTER_TO_UINT(NULL) == 0 > > > > across all platforms?
