#include <sched.h>int sched_yield(void)
DESCRIPTION
A process can relinquish the processor voluntarily without blocking by callingsched_yield().%uA0该过程将被移到队列的末尾，它的静态优先级和一个新的过程变得运行。Note: If the current process is the only process in the highest priority list at that time, this process will continue to run after a call to%uA0sched_yield().
POSIX systems on which%uA0sched_yield() is available define_POSIX_PRIORITY_SCHEDULING%uA0in <unistd.h>.
返回值
On success,%uA0sched_yield() returns 0. On error, -1 is returned, and%uA0errno%uA0is set appropriately.遵循于
