DESCRIPTION

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)
ERRORS
On Linux, this call always succeeds (but portable and future-proof applications should nevertheless handle a possible error return).
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

CONFORMING TO
This call is nonstandard, but present on several other systems. Use the standardized sched_yield(2) instead.
NOTES
On Linux, this function is implemented as a call to sched_yield(2).
pthread_yield() is intended
for use with real-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.
