It sure would be useful, though, if there were a construct that does mean "pointer to packed T". In particular, I've often needed "pointer to packed int" and found no way to produce that. I ended up creating a one-member struct with a packed int inside, which is a syntactic nightmare. (The application was a piece of legacy code that was writing via int pointers, but sometimes things were not aligned. The fix was much more invasive than it should have been because I could find no way to define a pointer to packed int.) If there IS a way to do that, it sure would be nice for the docs to explain it. Right now the documentation of "packed" is essentially unintellegible.
According to the docs here: <http://gcc.gnu.org/onlinedocs/gcc-3.4.3/gcc/Type-Attributes.html#Type-Attributes>
what about doing something like this?:
------------------------------------------- typedef int packed_int __attribute__ ((aligned (1)));
packed_int *ppi;
-------------------------------------------
