.B int pthread_yield(void);
.fi
.sp
Compile and link with \fI\-pthread\fP.
.SH DESCRIPTION
.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 CONFORMING TO
This call is nonstandard, but present on several other systems.
Use the standardized
.BR sched_yield (2)
instead.
.\" e.g., the BSDs, Tru64, AIX, and Irix.
.SH NOTES
On Linux, this function is implemented as a call to
.BR sched_yield (2).
