DAQmxWriteDigitalScalarU32

int32 DAQmxWriteDigitalScalarU32 (TaskHandle taskHandle, bool32 autoStart, float64 timeout, uInt32 value, bool32 *reserved);

Purpose

Writes a single 32-bit unsigned integer sample to a task that contains a single digital output channel. Use this format for devices with up to 32 lines per port.

Parameters

Input
Name	Type	Description
taskHandle	TaskHandle	The task to write the sample to.
autoStart	bool32	Specifies whether or not this function automatically starts the task if you do not start it.
timeout	float64	The amount of time, in seconds, to wait for this function to write the value. The default value is 10.0 seconds. To specify an infinite wait, pass -1 (DAQmx_Val_WaitInfinitely). This function returns an error if the timeout elapses. A value of 0 indicates to try once to write the value. If this function successfully writes the value, it does not return an error. Otherwise, the function returns a timeout error.
value	uInt32	A 32-bit integer sample to write to the task.
reserved	bool32 *	Reserved for future use. Pass NULL to this parameter.

Return Value

Name	Type	Description
status	int32	The error code returned by the function in the event of an error or warning. A value of 0 indicates success. A positive value indicates a warning. A negative value indicates an error.
