Get Attributes

RFmxLTE_GetAttributeString

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

Purpose

Queries the value of an RFmx string 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.

Parameters

Input
Name Type Description
instrumentHandle niRFmxInstrHandle Specifies the instrument session. The RFmx obtains this parameter from the RFmxLTE_Initialize) function.
selectorString char[] Specifies the selector string for the attribute being read. Refer to the Selector String (C/CVI)) topic for more information about configuring the selector string.

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.

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.

Parameters

Input
Name Type Description
instrumentHandle niRFmxInstrHandle Specifies the instrument session. The RFmx obtains this parameter from the RFmxLTE_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 NIComplexSingle[] 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.

Return Value

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 RFmxLTE_GetError) function.

The general meaning of the status code is as follows:
Value Meaning
0 Success
Positive Values Warnings
Negative Values Errors

RFmxLTE_GetAttributeNIComplexDoubleArray

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

Purpose

Queries 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.

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 NIComplexDouble[] 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.

Return Value
