#include <sched.h>

int sched_yield(void);

DESCRIPTION

A process can relinquish the processor voluntarily without blocking by callingsched_yield(). 該過程將被移到佇列的末尾，它的靜態優先順序和一個新的過程變得執行。

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 sched_yield().

POSIX systems on which sched_yield() is available define_POSIX_PRIORITY_SCHEDULING in <unistd.h>.

返回值

On success, sched_yield() returns 0. On error, -1 is returned, and errno is set appropriately.
