thread(9s)thread(9s)NAMEthread - General: Contains kernel threads-related information
SYNOPSIS
────────────────────────────
Member Name Data Type
────────────────────────────
wait_result kern_return_t
────────────────────────────
MEMBERS
Specifies the outcome of the wait. The kernel can set this member to
one of the following values: THREAD_AWAKENED, THREAD_INTERRUPTED,
THREAD_TIMED_OUT, THREAD_SHOULD_TERMINATE, and THREAD_RESTART.
DESCRIPTION
The thread data structure contains kernel threads-related information.
Kernel modules typically use the wait_result member (with the cur‐
rent_thread routine) to check for the result of the wait. The values
associated with the wait_result member have the following meanings: The
result of the assert wait is a normal wakeup. The wait condition was
interrupted by the clear_wait routine. The specified timeout has
expired. The result of the assert wait is that the current kernel
thread should terminate. The current kernel thread should be
restarted.
NOTES
The header file <thread.h> shows a typedef statement that assigns the
alternate name thread_t for a pointer to the thread data structure.
Many of the kernel threads-related routines operate on these pointers
to thread data structures.
The thread data structure is an opaque data structure; that is, all of
its associated members (except for the wait_result member) are refer‐
enced and manipulated by the operating system and not by the user of
kernel threads.
