Create AI Voltage Channel.

data type	parameter	describe
const char*	task	Task name.
const char*	chans	Channel list, Use commas to separate multiple channels or use colons to specify multiple channels in a row, such as "dev1/AIN1,dev1/AIN2,dev1/AIN3,dev1/AIN4", "dev1/AIN1:4", etc. Obtain Raw value: prefix RAW before AIN channel, for example: AIN1 returns Raw value, AIN2 returns voltage value "dev1/RAWAIN1, dev1/AIN2"
const char*	reserved1	Reserved.
int32_t	terminalConfig	The input terminal configuration for the channel. 0: SingleEnded. 1: Differential
double	minVal	The minimum value, in units, that you expect to measure.
double	maxVal	The maximum value, in units, that you expect to measure.
int32_t	units	Unit. 0: V
const char*	reserved2	Reserved.

Returns

On success, return value >= 0.

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