thread_block(9r)thread_block(9r)NAMEthread_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
