daqSetTimeout

Also See: daqWaitForEvent, daqWaitForEvents,

daqAdcTransferBufData, daqAdcRdN

Format

daqSetTimeout (handle, mSecTimeout)

Purpose

daqSetTimeout sets the time-out for waiting on either a single event or multiple events.

Parameter Summary

Parameter Type Description

handle DaqHandleT

Handle to the device for which the event time-out is to be set

mSecTimeout DWORD

Specifies time-out (in milliseconds) for events

Parameter Values

handle: obtained from the DaqOpen function

mSecTimeout: valid values range from 1 to 4,294,967,295; however, large values will cause timeout to be

excessively long

Function Usage

The daqSetTimeout function can be used in conjunction with the daqWaitForEvent and

daqWaitForEvents functions to specify a maximum amount of time to wait for the event(s) to be satisfied.

The mSecTimeout parameter specifies the maximum amount of time (in milliseconds) to wait for the event(s) to

occur. If the event(s) do not occur within the specified time-out, the daqWaitForEvent and/or

daqWaitForEvents will return.

If this function is not called, a default timeout of 10,000 milleseconds (10 seconds) will be used.

The daqSetTimeout function can be used for daqAdcRdN functions.

Returns

DerrNoError No error

Prototypes

C/C++

daqSetTimeout(DaqHandleT handle, DWORD mSecTimeout);

Visual BASIC
