* See i386-fbsd.c for copyright and license terms.
|
|
*
|
|
* System call arguments come in several flavours:
|
|
* Hex -- values that should be printed in hex (addresses)
|
|
* Octal -- Same as above, but octal
|
|
* Int -- normal integer values (file descriptors, for example)
|
|
* LongHex -- long value that should be printed in hex
|
|
* Name -- pointer to a NULL-terminated string.
|
|
* BinString -- pointer to an array of chars, printed via strvisx().
|
|
* Ptr -- pointer to some unspecified structure. Just print as hex for now.
|
|
* Stat -- a pointer to a stat buffer. Prints a couple fields.
|
|
* Stat11 -- a pointer to a freebsd 11 stat buffer. Prints a couple fields.
|
|
* StatFs -- a pointer to a statfs buffer. Prints a few fields.
|
|
* Ioctl -- an ioctl command. Woefully limited.
|
|
* Quad -- a double-word value. e.g., lseek(int, offset_t, int)
|
|
* Signal -- a signal number. Prints the signal name (SIGxxx)
|
|
* Sockaddr -- a pointer to a struct sockaddr. Prints symbolic AF, and IP:Port
|
|
* StringArray -- a pointer to an array of string pointers.
|
|
* Timespec -- a pointer to a struct timespec. Prints both elements.
|
|
* Timeval -- a pointer to a struct timeval. Prints both elements.
|
|
* Timeval2 -- a pointer to two struct timevals. Prints both elements of both.
|
|
* Itimerval -- a pointer to a struct itimerval. Prints all elements.
|
|
* Pollfd -- a pointer to an array of struct pollfd. Prints .fd and .events.
|
|
* Fd_set -- a pointer to an array of fd_set. Prints the fds that are set.
|
|
* Sigaction -- a pointer to a struct sigaction. Prints all elements.
|
|
* Sigset -- a pointer to a sigset_t. Prints the signals that are set.
|
|
* Sigprocmask -- the first argument to sigprocmask(). Prints the name.
|
|
* Kevent -- a pointer to an array of struct kevents. Prints all elements.
|
|
* Pathconf -- the 2nd argument of pathconf().
|
|
* Utrace -- utrace(2) buffer.
|
|
* CapRights -- a pointer to a cap_rights_t. Prints all set capabilities.
|
|
*
|
|
* In addition, the pointer types (String, Ptr) may have OUT masked in --
|
|
* this means that the data is set on *return* from the system call -- or
|
|
* IN (meaning that the data is passed *into* the system call).
