You are trying to take the address of a pointer and pass that. The compiler usually does the right thing, knowing that this is a common error. I use sscanf regularly without any warnings although I am not sure I have tried it with the latest intel C compiler. Try dumping the &'s in the above first to see if that fixes the problem... >I use it to read the winboard command after level(can be not more than 9 even in >the extended level command). >There were no problems with it but for some reasons the intel compiler see >problems. > >For now there is no speed change from the intel compiler but I still did not >learn how to do profile optimization and I use only optimize for speed. > >Uri
