daqSetTimeout
DLL Function daqSetTimeout(DaqHandleT handle, DWORD mSecTimeout);
C daqSetTimeout(DaqHandleT handle, DWORD mSecTimeout);
Visual BASIC VBdaqSetTimeout&(ByVal handle&, ByVal mSecTimeout&)
Delphi daqSetTimeout(handle:DaqHandleT; mSecTimeout:DWORD)
Parameters
handle Handle to the device for which the event time-out is to be set
mSecTimeout Specifies time-out ( ms ) for events
Returns DerrNoError - No error (also, refer to API Error Codes on page 11-39)
See Also daqWaitForEvent, daqWaitForEvents
Program References None
Used With All devices
daqSetTimeout allows you to set the time-out for waiting on a single event or multiple events.
This 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.
