NAME    [Toc]    [Back]

       thread - General: Contains kernel threads-related information

SYNOPSIS    [Toc]    [Back]

       ----------------------------
       Member Name   Data Type

       wait_result   kern_return_t

MEMBERS    [Toc]    [Back]

       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    [Toc]    [Back]

       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: 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    [Toc]    [Back]

       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.
