pthread_yield(3)         Library Functions Manualpthread_yield(3)

NAME        top

       pthread_yield - yield the processor

LIBRARY        top

       POSIX threads library (libpthread,-lpthread)

SYNOPSIS        top

#define _GNU_SOURCE/* See feature_test_macros(7) */#include <pthread.h>[[deprecated]] int pthread_yield(void);

DESCRIPTION        top

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, seesched_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

       For an explanation of the terms used in this section, seeattributes(7).       ┌──────────────────────────────────────┬───────────────┬─────────┐       │Interface│Attribute│Value│       ├──────────────────────────────────────┼───────────────┼─────────┤       │pthread_yield()                      │ Thread safety │ MT-Safe │       └──────────────────────────────────────┴───────────────┴─────────┘

VERSIONS        top

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

STANDARDS        top

       None.

HISTORY        top

       Deprecated since glibc 2.34.  Use the standardizedsched_yield(2)       instead.

NOTES        top

pthread_yield() is intended for use with real-time scheduling       policies (i.e.,SCHED_FIFOorSCHED_RR).  Use ofpthread_yield()       with nondeterministic scheduling policies such asSCHED_OTHERis       unspecified and very likely means your application design is       broken.
