* Ptr -- pointer to some specific structure. Just print as hex for now.
* Quad -- a double-word value. e.g., lseek(int, offset_t, int)
* Stat -- a pointer to a stat buffer. Currently unused.
* Ioctl -- an ioctl command. Woefully limited.
*
* In addition, the pointer types (String, Ptr) may have OUT masked in --
* this means that the data is set on *return* from the system call -- or
