Owning Palette: Memory Control Functions

Requires: Base Development System

Removes LabVIEW access to the data that the data value reference or the external data value reference points to. This function deletes the reference but leaves the data intact. Memory leakage might occur if you do not delete the reference.

Note  You must use this function to delete an external data value reference and release the associated memory to the device driver that supports and provides the reference; otherwise, the hardware does not have access to that buffer space.


data value reference points to the data you want to recover. LabVIEW deletes this reference after you recover the data. Use the New Data Value Reference function to create a data value reference.
error in describes error conditions that occur before this node runs. With the following exception, this input provides standard error in functionality.

This node runs normally even if an error occurred before this node runs.
data value is the data the reference points to.
error out contains error information. This output provides standard error out functionality.

Delete Data Value Reference Details

To avoid data copies, leave the data value output of this function unwired when working with external data value references.
