thread_block(9r)					      thread_block(9r)

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

SYNOPSIS
       void thread_block(
	       void );

ARGUMENTS
       None

DESCRIPTION
       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  gen‐
       eral, 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
       None
