public enum ReadWaitMode

Public Enumeration ReadWaitMode

Member name	Value	Description
WaitForInterrupt	12523	Check for available samples when the system receives an interrupt service request. This mode is the most CPU efficient, but results in lower possible sampling rates.
Poll	12524	Repeatedly check for available samples as fast as possible. This mode allows for the highest sampling rates at the expense of CPU efficiency.
Yield	12525	Repeatedly check for available samples, but yield control to other threads after each check. This mode offers a balance between sampling rate and CPU efficiency.
Sleep	12547	Check for available samples once per the amount of time specified in ReadSleepTime.

Specifies how reading from the task waits for samples to become available. Use this enumeration to get or set the value of ReadWaitMode.
