NAME    [Toc]    [Back]

       thread_block - General: Blocks (puts to sleep) the current
       kernel thread

SYNOPSIS    [Toc]    [Back]

       void thread_block(
               void );

ARGUMENTS    [Toc]    [Back]

       None

DESCRIPTION    [Toc]    [Back]

       The thread_block routine blocks (puts to sleep)  the  current
  kernel  thread and selects the next kernel thread to
       start (run). The routine schedules the next kernel  thread
       onto this CPU.

       When  a  kernel  thread is waiting for an event, it should
       block. In general, a kernel thread  is  blocked  when  the
       thread wait bit in the thread structure pointer associated
       with the current kernel thread is set. This bit  signifies
       that  this  kernel  thread is on the appropriate wait hash
       queue, waiting for a wakeup call. This allows the  CPU  to
       execute  another kernel thread while this kernel thread is
       blocked.

RETURN VALUES    [Toc]    [Back]

       None
