11-32 daqCommand Reference (Enhanced API) TempBook User’s Manual
The count parameter can be used to indicate the duration or length of the test. For instance, a
resource test will be run count times; and if any one iteration of the test fails, it will indicate an
overall failure of the test. For a performance test, the count parameter will indicate the number of
times to run the test, and the test result will be an average of all the tests performed.
daqWaitForEvent
DLL Function daqWaitForEvent(DaqHandleT handle, DaqTransferEvent daqEvent);
C daqWaitForEvent(DaqHandleT handle, DaqTransferEvent daqEvent);
Visual BASIC VBdaqWaitForEvent&(ByVal handle&, ByVal daqEvent&)
Delphi daqWaitForEvent(handle:DaqHandleT; daqEvent:DaqTransferEvent)
Parameters
handle Handle of the device for which to wait of the specified event
daqEvent Specifies the event to wait on
Returns DerrNoError - No error (also, refer to API Error Codes on page 11-39)
See Also daqWaitForEvents, daqSetTimout
Program References ADCEX1.C, DACEX1.C, DYN32ENH.C, DAQEX.FRM (VB), ADCEX.PAS (Delphi)
Used With All devices
daqWaitForEvent allows you to wait on a specific Daq* event to occur on the specified device.
This function will not return until the specified event has occurred or the wait has timed out—
whichever comes first. The event time-out can be set with the daqSetTimout function. See the
Transfer Event Definitions table for event definitions.
daqWaitForEvents
DLL Function daqWaitForEvents(DaqHandleT *handles, DaqTransferEvent *daqEvents,
DWORD eventCount, BOOL *eventSet, DaqWaitMode waitMode);
C daqWaitForEvents(DaqHandleT *handles, DaqTransferEvent *daqEvents,
DWORD eventCount, BOOL *eventSet, DaqWaitMode waitMode);
Visual BASIC VBdaqWaitForEvents&(handles&(), daqEvents&(), ByVal eventCount&, eventSet&(),
ByVal waitMode&)
Delphi daqWaitForEvents(handles:DaqHandlePT; daqEvents:DaqTransferEventP;
eventCount:DWORD; eventSet:PLONGBOOL; waitMode:DaqWaitMode)
Parameters
*handles Pointer to an array of handles which represent the list of device on which to wait for the events
*daqEvents Pointer to an array of events which represents the list of events to wait on
eventCount Number of defined events to wait on
*eventSet Pointer to an array of Booleans indicating if the events have been satisfied.
waitMode Specifies the mode for the wait
Returns DerrNoError - No error (also, refer to API Error Codes on page 11-39)

Used With All devices
daqWaitForEvents allows you to wait on specific Daq* events to occur on the specified
devices. This function will wait on the specified events and will return based upon the criteria
selected with the waitMode parameter. A time-out for all events can be specified using the
daqSetTimeout
command.
Events to wait on are specified by passing an array of event definitions in the events parameter.
The number of events is specified with the eventCount parameter. See the Transfer Event
Definitions table for events parameter definitions. Also see the Transfer Event Wait Mode
Definitions table for waitMode parameter definitions.
