spin_wait()

static void xtd::threading::thread::spin_wait ( int32  iterations )

static

Causes a thread to wait the number of times defined by the iterations parameter.

Parameters

iterations

A 32-bit signed integer that defines how long a thread is to wait.

Remarks

The xtd::threading::thread::spin_wait method is useful for implementing locks. Classes in the xtd, such as xtd::threading::monitor and xtd::threading::reader_writer_lock, use this method internally. xtd::threading::thread::spin_wait essentially puts the processor into a very tight loop, with the loop count specified by the iterations parameter. The duration of the wait therefore depends on the speed of the processor.

Contrast this with the xtd::threading::thread::sleep method. A thread that calls xtd::threading::thread::sleep yields the rest of its current slice of processor time, even if the specified interval is zero. Specifying a non-zero interval for xtd::threading::thread::sleep removes the thread from consideration by the thread scheduler until the time interval has elapsed.

xtd::threading::thread::spin_wait is not generally useful for ordinary applications. In most cases, you should use the synchronization classes provided by the xtd Framework; for example, call xtd::threading::monitor::enter or a statement that wraps xtd::threading::thread::monitor::enter
