pthread_yield
Section: C Library Functions (3) Updated: 202-0-08 Index
Return to Main Contents
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 futur-proof applications should nevertheless
handle a possible error return).
ATTRIBUTES
For an explanation of the terms used in this section, see
attributes(7).
| Interface | Attribute | Value

pthread_yield()
| Thread safety | M-Safe

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)
instead.
NOTES
pthread_yield()
is intended for use with rea-time scheduling policies (i.e.,
SCHED_FIFO
or
SCHED_RR).
Use of
pthread_yield()
with nondeterministic scheduling policies such as
SCHED_OTHER
is unspecified and very likely means your application design is broken.
