+.SH DESCRIPTION
+.BR Note :
+This function is deprecated; see below.
+.P
+.BR 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
+.BR sched_yield (2)
+.SH RETURN VALUE
+On success,
+.BR pthread_yield ()
+returns 0;
+on error, it returns an error number.
+.SH ERRORS
+On Linux, this call always succeeds
+(but portable and future-proof applications should nevertheless
+handle a possible error return).
+.SH ATTRIBUTES

+.SH VERSIONS
+On Linux, this function is implemented as a call to
+.BR sched_yield (2).
+.SH STANDARDS
+None.
+.SH HISTORY
+.\" BSD, Tru64, AIX, and Irix.
+Deprecated since glibc 2.34.
+Use the standardized
+.BR sched_yield (2)
+instead.
+.SH NOTES
+.BR pthread_yield ()
+is intended for use with real-time scheduling policies (i.e.,
+.B SCHED_FIFO
+or
+.BR SCHED_RR ).
+Use of
+.BR pthread_yield ()
+with nondeterministic scheduling policies such as
+.B SCHED_OTHER
+is unspecified and very likely means your application design is broken.
