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 * 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 * StatFs -- a pointer to a statfs buffer. Prints a few fields.
14 * Ioctl -- an ioctl command. Woefully limited.
15 * Quad -- a double-word value. e.g., lseek(int, offset_t, int)
16 * Signal -- a signal number. Prints the signal name (SIGxxx)
17 * Sockaddr -- a pointer to a struct sockaddr. Prints symbolic AF, and IP:Port
18 * StringArray -- a pointer to an array of string pointers.
19 * Timespec -- a pointer to a struct timespec. Prints both elements.
20 * Timeval -- a pointer to a struct timeval. Prints both elements.
21 * Timeval2 -- a pointer to two struct timevals. Prints both elements of both.
22 * Itimerval -- a pointer to a struct itimerval. Prints all elements.
23 * Pollfd -- a pointer to an array of struct pollfd. Prints .fd and .events.
24 * Fd_set -- a pointer to an array of fd_set. Prints the fds that are set.
25 * Sigaction -- a pointer to a struct sigaction. Prints all elements.
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 * Utrace -- utrace(2) buffer.
32 * In addition, the pointer types (String, Ptr) may have OUT masked in --
33 * this means that the data is set on *return* from the system call -- or
34 * IN (meaning that the data is passed *into* the system call).
