Yes, but to be safe, you need to use void * as an intermediate type in the conversion. BTW, this does not mean that the conversion is lossless, as I suppose that a pointer type may carry more information than just the address of the object. But I think that this does not matter here. -- Vincent Lefèvre <vincent@xxxxxxxxxx> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
