.SH NOTES
On Linux, this function is implemented as a call to
.BR sched_yield (2).
.PP
.BR pthread_yield ()
is intended for use with read-time scheduling policies (i.e.,
.BR SCHED_FIFO
or
.BR SCHED_RR ).
Use of
.BR pthread_yield ()
with nondeterministic scheduling policies such as
.BR SCHED_OTHER
is unspecified and very likely means your application design is broken.

.BR pthreads (7),
