Hi,
I tried the code below:
struct task_events_info taskevents;
size_t tkcount = TASK_EVENTS_INFO_COUNT;
error_t err;
err = task_info (mach_task_self (), TASK_EVENTS_INFO,
(task_info_t) &taskevents, &tkcount);
assert_perror (err);
and I always get the error:
Unexpected error: (os/kern) invalid argument.
It seems to me that the Mach doesn't support TASK_EVENTS_INFO.
I read Mach 3 Kernel Interfaces and it seems that the original Mach only
supports TASK_BASIC_INFO and TASK_THREAD_TIMES_INFO, but The GNU Mach
Reference Manual mentions TASK_EVENTS_INFO. I assume that this feature
is added in GNU Mach.
I use Debian/Hurd, and the version of Mach is GNU Mach 1.3.99. I wonder
which version of GNU Mach supports TASK_EVENTS_INFO.
Best regards,
Zheng Da
