Returns a string attribute specified by the attribute ID parameter for a device specified by the session in and index in parameters.

The session in parameter is expected to be a valid handle returned by niModInst Open Installed Devices Session. Therefore, this parameter acts as a handle to a list of installed devices. The index in parameter specifies the device in the list for which you want the attribute.

  • cgenclassrn.png session in —

    session in is the NI-ModInst session handle created by niModInst Open Installed Devices Session.

  • ci32.png index in —

    index in is a zero-based index that specifies the device for which you want the attribute.

    The index in parameter should be between 0 and (device count – 1), inclusive, where device count is the number of installed devices returned by niModinst Open Installed Devices Session.

  • ci32.png attribute ID —

    attribute ID is the ID of the string attribute you want to query.

    Valid Values

    Device Name—the name of the device, which can be used to open an instrument driver session for that device

    Device Model—the model of the device (for example, NI PXI-5122)

    Serial Number—the serial number of the device

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this VI or function runs.

  • igenclassrn.png session out —

    session out has the same value as session in.

  • ii32.png index out —

    index out has the same value as index in.

  • istr.png attribute value —

    attribute value returns the value of the requested attribute.

  • ierrcodeclst.png error out —
