pthread_yield(3) Library Functions Manual pthread_yield(3)
NAME
pthread_yield - yield the processor
LIBRARY
POSIX threads library (libpthread, -lpthread)
SYNOPSIS
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <pthread.h>
[[deprecated]] int pthread_yield(void);
DESCRIPTION
Note: This function is deprecated; see below.
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 ap-
plications should nevertheless handle a possible error return).
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

VERSIONS
On Linux, this function is implemented as a call to sched_yield(2).
STANDARDS
None.
HISTORY
Deprecated since glibc 2.34. Use the standardized sched_yield(2) in-
stead.
NOTES
pthread_yield() is intended for use with real-time scheduling policies
(i.e., SCHED_FIFO or SCHED_RR). Use of pthread_yield() with nondeter-
ministic scheduling policies such as SCHED_OTHER is unspecified and very
likely means your application design is broken.
