1/*
2 * System call arguments come in several flavours:
3 * Hex -- values that should be printed in hex (addresses)
4 * Octal -- Same as above, but octal
5 * Int -- normal integer values (file descriptors, for example)
6 * String -- pointers to sensible data. Note that we treat read() and
7 * write() arguments as such, even though they may *not* be
8 * printable data.
9 * Ptr -- pointer to some specific structure. Just print as hex for now.
10 * Quad -- a double-word value. e.g., lseek(int, offset_t, int)
11 * Stat -- a pointer to a stat buffer. Currently unused.

13 * In addition, the pointer types (String, Ptr) may have OUT masked in --
14 * this means that the data is set on *return* from the system call -- or
15 * IN (meaning that the data is passed *into* the system call).
