niRFSA_GetAttributeViInt64
ViStatus niRFSA_GetAttributeViInt64(ViSession vi, ViConstString channelName, ViAttr attributeId, ViInt64 *value);
Purpose
Queries the value of a ViInt64 attribute.
You can use this low-level function to get the values of inherent IVI attributes and instrument-specific attributes.
Supported Devices: PXI-5600, PXIe-5601/5603/5605/5606 (external digitizer mode), PXIe-5644/5645/5646, PXI-5661, PXIe-5663/5663E/5665/5667/5668, PXIe-5693/5694/5698, PXIe-5820/5830/5831/5832/5840/5841/5842

| vi | ViSession | Identifies your instrument session. vi is obtained from the niRFSA_init or niRFSA_InitWithOptions function. |
| channelName | ViConstString | Specifies the name of the channel on which to check the attribute value if the attribute is channel based. If the attribute is not channel based, set this parameter to "" (empty string) or VI_NULL. |
| attributeId | ViAttr | Pass the ID of an attribute. |
| Output | ||
| Name | Type | Description |
| value | ViInt64* | Returns the current value of the attribute. Pass the address of a ViInt64 variable. |
Return Value
| Name | Type | Description | ||||||||
| status | ViStatus | 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 NI-RFSA 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 niRFSA_GetError function. To clear the error information from NI-RFSA, call the niRFSA_ClearError function. The general meaning of the status code is as follows:
