PTHREAD_YIELD(3)          Linux Programmer's Manual         PTHREAD_YIELD(3)

NAME         top

       pthread_yield - yield the processor

SYNOPSIS         top

       #define _GNU_SOURCE             /* See feature_test_macros(7) */
       #include <pthread.h>

       int pthread_yield(void);

       Compile and link with -pthread.

DESCRIPTION         top

       pthread_yield() causes the calling thread to relinquish the CPU.  The
       thread is placed at the end of the run queue for its static priority
       and another thread is scheduled to run.  For further details, see
       sched_yield(2)

RETURN VALUE         top

       On success, pthread_yield() returns 0; on error, it returns an error
       number.

ERRORS         top

       On Linux, this call always succeeds (but portable and future-proof
       applications should nevertheless handle a possible error return).

ATTRIBUTES         top

   Multithreading (see pthreads(7))
       The pthread_yield() function is thread-safe.

CONFORMING TO         top

       This call is nonstandard, but present on several other systems.  Use
       the standardized sched_yield(2) instead.

NOTES         top

       On Linux, this function is implemented as a call to sched_yield(2).

SEE ALSO         top
