-thread_info
Function - Return information about a thread.
SYNOPSIS
kern_return_t thread_info
(thread_act_t target_thread,
thread_flavor_t flavor,
thread_info_t thread_info,
mach_msg_type_number_t thread_info_count);
PARAMETERS
- target_thread
-
[in thread send right]
The thread for which the information is to be
returned.
- flavor
-
[in scalar]
The type of information to be returned. Valid values are:
- THREAD_BASIC_INFO
-
Returns basic information about the thread, such as the
thread's run state and suspend count. The returned structure is
thread_basic_info.
- THREAD_SCHED_FIFO_INFO
-
Returns FIFO scheduling policy information about the thread.
The returned structure is policy_fifo_info.
- THREAD_SCHED_RR_INFO
-
Returns round-robin scheduling policy information about the
thread. The returned structure is policy_rr_info.
- THREAD_SCHED_TIMESHARE_INFO
-
Returns timeshare scheduling policy information about the
thread. The returned structure is policy_timeshare_info.
- thread_info
-
[out structure]
Information about the specified thread.
- thread_info_count
-
[in/out scalar]
On input, the maximum size of the buffer; on output, the
size returned (in natural-sized units).
DESCRIPTION
The thread_info function returns an information structure
of type flavor.
NOTES
At any given time, a thread has only one scheduling policy in
effect for it. Thus,
only one of the scheduling information structures will be valid,
that so indicated
by the policy value returned by THREAD_BASIC_INFO.
RETURN VALUES
Only generic errors apply.
