int32 __stdcall RFmxNR_SetAttributeNIComplexDoubleArray (niRFmxInstrHandle instrumentHandle, char selectorString[], int32 attributeID, NIComplexDouble attrVal[], int32 arraySize);

Sets the value of an RFmx NIComplexDouble attribute. You must provide a char array to serve as a buffer for the value. Pass the number of bytes in the buffer as the arraySize parameter. If you want to call this function just to get the required buffer size, you must pass 0 for arraySize and NULL for the attrVal buffer.

If the current value of the attribute, including the terminating NULL byte, is larger than the size you indicate in the arraySize parameter, the function copies buffer size - 1 bytes into the buffer, places an ASCII NULL byte at the end of the buffer, and returns the buffer size you must pass to get the entire value. For example, if the value is "123456" and the buffer size is 4, the function places "123" into the buffer and returns 7.

If you want to call this function just to get the required buffer size, you must pass 0 for arraySize and NULL for the attrVal buffer.

If the current value of the attribute, including the terminating NULL byte, is larger than the size you indicate in the arraySize parameter, the function copies buffer size - 1 bytes into the buffer, places an ASCII NULL byte at the end of the buffer, and returns the buffer size you must pass to get the entire value. For example, if the value is "123456" and the buffer size is 4, the function places "123" into the buffer and returns 7.

Input
Name	Type	Description
instrumentHandle	niRFmxInstrHandle	Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxNR_Initialize) function.
selectorString	char[]	Specifies the selector string for the attribute being set. Refer to the Selector String (C/CVI)) topic for more information about configuring the selector string.
attributeID	int32	Pass the ID of an attribute.
arraySize	int32	Specifies the size of the array. Set the arraySize parameter to 0 to get the size of all the arrays in the actualArraySize parameter.
Output
Name	Type	Description
attrVal	float64[]	Returns the current value of the attribute.
actualArraySize	int32*	Returns the actual size of the array, if you pass NULL to all output array parameters, and set the arraySize parameter to 0.

Name	Type	Description
status	int32	Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an RFmx function to determine if an error has occurred. To obtain a text description of the status code and additional information about the error condition, call the RFmxNR_GetError) function. The general meaning of the status code is as follows:

Value	Meaning
0	Success
Positive Values	Warnings
Negative Values	Errors

int32 __stdcall RFmxNR_GetAttributeNIComplexSingleArray (niRFmxInstrHandle instrumentHandle, char selectorString[], int32 attributeID, NIComplexSingle attrVal[], int32 arraySize, int32 *actualArraySize);

Queries the value of an RFmx NIComplexSingle attribute. You must provide a char array to serve as a buffer for the value. Pass the number of bytes in the buffer as the arraySize parameter. If you want to call this function just to get the required buffer size, you must pass 0 for arraySize and NULL for the attrVal buffer.
