    yeah, that'll work so long as you don't stash your structs pointers this way. :)

      The cast operator is why I can cast my struct directly to an "array" of bytes and stash it in a file. It makes me happy. It's so elegant. So concise. And so dangerous.

      the file is also not compatible between architecture to the next! :( i.e. endianess for sure.. but probably computer struct paddings too! :/ though haven't used C in decades, so I am not so sure about that one...

        Sometimes that doesn't matter. Sometimes you're writing software dedicated to a particular microcontroller and it expects the thing to be wired a certain way in order to run anyway.

                Yeah, but that processing the struct after-the-fact. Her technique is great for 'simple' structs.

                        I have been using C for+/- 32 years and still like it a lot. The fact that yes, you can do anything, does force you to be very careful what you ask for because you will get it. :-\

                          Neither did I, until I discovered I "was using it wrong" and had some "true C++ programmer" abusing templates lambda functions like there was no tomorrow.

                              You could always use a union, no need to even cast then (: I wouldn't want to program in C targeting a PC these days; but it is good for 8 & 16 bit embedded work, where you need to get at hardware registers and only have maybe 2K RAM and 16K or 32K ROM.

                                    I use unions sometimes, but i only needed the cast in two places in the code that inspired this post, and it was all it was ever going to need. :)

                                    I really liked being able to cast nearly anything to anything. For a cheap and easy (and not too secure) 'encryption' I'd just do something like:

                                    union {
                                    char * readable;
                                    ulong * notSoMuch;
                                    }

                                    and then you can trivially make a string unreadable by storing the int array in a text file (lots of options there, too, spaced or other-delimiters? left-zero-filled? Decryption is obvious - and really no overhead as all - I always though of it as the string and its encrypted version coexisting in different planes of their little universe.

                                      I use the union technique for that in both C(++) and C#. I don't *always* use it in the former just because i hate declaring new types for one or two lines of code where it will be used. i don't really believe in security by obscurity in most cases, but it may be useful for shrouding source code.

                                        You could always use a union, no need to even cast then (: I wouldn't want to program in C targeting a PC these days; but it is good for 8 & 16 bit embedded work, where you need to get at hardware registers and only have maybe 2K RAM and 16K or 32K ROM.

                                        I'm coding a microcontroller and technically I'm using C++ but barely because I am avoiding templates and the STL. =(

                                          I have been using C for+/- 32 years and still like it a lot. The fact that yes, you can do anything, does force you to be very careful what you ask for because you will get it. :-\

                                          It's very satisfying to be back to it after being confined to coding in C# so much.
