Mikael Djurfeldt <mdj@nada.kth.se> writes: [good reasons why a swiss army realloc isn't a good idea] It probably isn't a good idea (I was more looking for an excuse to spend some time with the gc, I think ;). It does, however, correspond to the way that glibc's realloc works, at least when a NULL pointer is given, so on those systems, you can currently use it as a malloc anyway (this probably isn't the greatest idea). I've no particular attachment to that behaviour, though. What I'm more interested in is figuring out how to get the space allocated to a given pointer with mallocs besides glibc's. -- Greg
