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



NAME
       pthread_yield - yield the processor

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

       int pthread_yield(void);

       Compile and link with -pthread.

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

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

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

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

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