2 * See i386-fbsd.c for copyright and license terms.
3 *
4 * System call arguments come in several flavours:
5 * Hex -- values that should be printed in hex (addresses)
6 * Octal -- Same as above, but octal
7 * Int -- normal integer values (file descriptors, for example)
8 * LongHex -- long value that should be printed in hex
9 * Name -- pointer to a NULL-terminated string.
10 * BinString -- pointer to an array of chars, printed via strvisx().
11 * Ptr -- pointer to some unspecified structure.  Just print as hex for now.
12 * Stat -- a pointer to a stat buffer.  Prints a couple fields.
13 * Ioctl -- an ioctl command.  Woefully limited.
14 * Quad -- a double-word value.  e.g., lseek(int, offset_t, int)
15 * Signal -- a signal number.  Prints the signal name (SIGxxx)
16 * Sockaddr -- a pointer to a struct sockaddr.  Prints symbolic AF, and IP:Port
17 * StringArray -- a pointer to an array of string pointers.
18 * Timespec -- a pointer to a struct timespec.  Prints both elements.
19 * Timeval -- a pointer to a struct timeval.  Prints both elements.
20 * Timeval2 -- a pointer to two struct timevals.  Prints both elements of both.
21 * Itimerval -- a pointer to a struct itimerval.  Prints all elements.
22 * Pollfd -- a pointer to an array of struct pollfd.  Prints .fd and .events.
23 * Fd_set -- a pointer to an array of fd_set.  Prints the fds that are set.
24 * Sigaction -- a pointer to a struct sigaction.  Prints all elements.
25 * Umtx -- a pointer to a struct umtx.  Prints the value of owner.
26 * Sigset -- a pointer to a sigset_t.  Prints the signals that are set.
27 * Sigprocmask -- the first argument to sigprocmask().  Prints the name.
28 * Kevent -- a pointer to an array of struct kevents.  Prints all elements.
29 * Pathconf -- the 2nd argument of pathconf().
30 *
31 * In addition, the pointer types (String, Ptr) may have OUT masked in --
32 * this means that the data is set on *return* from the system call -- or
33 * IN (meaning that the data is passed *into* the system call).
