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