NAME
  thread - General: Contains kernel threads-related information

SYNOPSIS
  ___________________________
  Member Name	Data Type
  ___________________________
  wait_result	kern_return_t
  ___________________________

MEMBERS
  wait_result
      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
  current_thread routine) to check for the result of the wait. The values
  associated with the wait_result member have the following meanings:

  THREAD_AWAKENED
      The result of the assert wait is a normal wakeup.

  THREAD_INTERRUPTED
      The wait condition was interrupted by the clear_wait routine.

  THREAD_TIMED_OUT
      The specified timeout has expired.

  THREAD_SHOULD_TERMINATE
      The result of the assert wait is that the current kernel thread should
      terminate.

  THREAD_RESTART
      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 referenced and
  manipulated by the operating system and not by the user of kernel threads.
