37 * System call arguments come in several flavours:
38 * Hex -- values that should be printed in hex (addresses)
39 * Octal -- Same as above, but octal
40 * Int -- normal integer values (file descriptors, for example)
41 * LongHex -- long value that should be printed in hex
42 * Name -- pointer to a NULL-terminated string.
43 * BinString -- pointer to an array of chars, printed via strvisx().
44 * Ptr -- pointer to some unspecified structure. Just print as hex for now.
45 * Stat -- a pointer to a stat buffer. Prints a couple fields.
46 * Stat11 -- a pointer to a freebsd 11 stat buffer. Prints a couple fields.
47 * StatFs -- a pointer to a statfs buffer. Prints a few fields.
48 * Ioctl -- an ioctl command. Woefully limited.
49 * Quad -- a double-word value. e.g., lseek(int, offset_t, int)
50 * Signal -- a signal number. Prints the signal name (SIGxxx)
51 * Sockaddr -- a pointer to a struct sockaddr. Prints symbolic AF, and IP:Port
52 * StringArray -- a pointer to an array of string pointers.
53 * Timespec -- a pointer to a struct timespec. Prints both elements.
54 * Timeval -- a pointer to a struct timeval. Prints both elements.
55 * Timeval2 -- a pointer to two struct timevals. Prints both elements of both.
56 * Itimerval -- a pointer to a struct itimerval. Prints all elements.
57 * Pollfd -- a pointer to an array of struct pollfd. Prints .fd and .events.
58 * Fd_set -- a pointer to an array of fd_set. Prints the fds that are set.
59 * Sigaction -- a pointer to a struct sigaction. Prints all elements.
60 * Sigset -- a pointer to a sigset_t. Prints the signals that are set.
61 * Sigprocmask -- the first argument to sigprocmask(). Prints the name.
62 * Kevent -- a pointer to an array of struct kevents. Prints all elements.
63 * Pathconf -- the 2nd argument of pathconf().
64 * Utrace -- utrace(2) buffer.
65 * CapRights -- a pointer to a cap_rights_t. Prints all set capabilities.
67 * In addition, the pointer types (String, Ptr) may have OUT masked in --
68 * this means that the data is set on *return* from the system call -- or
69 * IN (meaning that the data is passed *into* the system call).
