Detailed Description

Function Documentation

VkDaqSetTaskStreamData()

int32_t VkDaqSetTaskStreamData	(	const char *	task,
		const double	dat[],
		int32_t	sampsPerChan,
		int32_t	fillmode,
		int32_t	autoStart,
		int32_t	stopAt,
		double	timeout
	)

Set task data.

data type	parameter	describe
const char*	task	Task name(string type, for example"Task1")
const double[]	dat[]	Task data buffer (doublearray pointer).
int32_t	sampsPerChan	The number of samples to be written to each channel (integer type).
int32_t	fillmode	Data arrangement: 0: interleaving (grouped by scan count) 1: Non interleaved (grouped by channel)
int32_t	autoStart	Waveform output control: 0: Do not output waveform 1: Output waveform
int32_t	stopAt	Waveform stop control: 0: When stopped, the output voltage is 0V 1: When stopped, the output voltage is the current voltage
double	timeout	Timeout time (unit: seconds,doubletype, supports sub second precision, for example0.5represents 500 milliseconds).

Returns

On success, return value >= 0.

On failure, returns a negative error number.For detail, please Call VkDaqGetLastErrorInfo
