With printf() it probably just works because it uses C-style varargs and 
the two elements of a char[] happen to both be the "native" size of the 
processor (so there's no padding inserted).
It may not even work on all platforms.

Also, AFAIK the compiler would be well within its rights to use the 
opposite order of .length and .ptr in memory; meaning that even if the C 
calling convention allows this the order they're passed in isn't guaranteed.
