What bearing does exporting a function have on whether it should check for NULL? Given that this function returns size_t, it can't return an error number. So what value would it return if "pool" were NULL? It can only return a positive integer or zero. Also, the argument should be const as the function doesn't modify the contents of "pool". -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up.
