preempt, yield —
#include <sys/sched.h>
void
preempt(void);
#include
<sys/proc.h>
void
yield(void);
preempt() function puts the current LWP back on the
system run queue and performs an involuntary context switch. The
yield() function is mostly same as
preempt(), except that it performs a voluntary context
switch.
These functions drop the kernel lock before switching and re-acquire it before returning.
