|
* 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
|
- Add decoding of kse_release, kevent, sigprocmask, unmount, socket, getrusage,
rename, __getcwd, shutdown, getrlimit, setrlimit, _umtx_lock, _umtx_unlock,
pathconf, truncate, ftruncate, kill
- Decode more arguments of open, mprot, *stat, and fcntl.
- Convert all constant-macro and bitfield decoding to lookup tables; much
cleaner than previous code.
- Print the timestamp of process exit and signal reception when -d or -D are in
use
- Try six times with 1/2 second delay to debug the child

|
|
* 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.
|

|
|
|
* StatFs -- a pointer to a statfs buffer. Prints a few fields.
|
1997-12-06 06:51:14 +00:00
|
|
|
* Ioctl -- an ioctl command. Woefully limited.
|
Add support for decoding Timespec, Timeval, Itimerval, Pollfd,
Fd_set and Sigaction structures. Use these for printing the arguments
to sigaction(), nanosleep(), select(), poll(), gettimeofday(),
clock_gettime(), recvfrom(), getitimer() and setitimer().
This is based on Dan's patch from the PR but I've hacked it for
style and some other issues. While Dan has checked this patch, any
goofs are probably my fault.
(The PR also contains support for the dual return values of pipe().
These will follow once I've ported that support to platforms other
than i386.)

|
* Quad -- a double-word value. e.g., lseek(int, offset_t, int)
|
|
|

|
|
|
|

|
|
|
|
* StringArray -- a pointer to an array of string pointers.
|
|
|
|
* Timespec -- a pointer to a struct timespec. Prints both elements.
|
|
|

- Decode the arguments for several signal-related system calls: sigpending,
sigqueue, sigreturn, sigsuspend, sigtimedwait, sigwait, sigwaitinfo, and
thr_kill.
- Print signal sets as a structure (with {}'s) and in particular use this to
differentiate empty sets from a NULL pointer.
- Decode arguments for some other system calls: issetugid, pipe2, sysarch
(operations are only decoded for amd64 and i386), and thr_self.
