Did you *really* zeroize that key?

[Rich Salz]

Probably moving out of the domain of the crypto list.

volatile, like const, is a storage-class modifier.  As written, it
means a pointer to memory that is volatile; this means, in particular,
that you can't optimize away dereferences.  If you wrote
        char * volatile foo;
That means that foo itself is volatile, and you must fetch it from
memory whenever you want its value.

You might find the cdecl program useful...

    ; cdecl
    Type `help' or `?' for help
    cdecl> explain volatile void* vp
    declare vp as pointer to volatile void
    cdecl> explain void * volatile vp
    declare vp as volatile pointer to void
    cdecl> explain volatile void * volatile vp
    declare vp as volatile pointer to volatile void
