Unlocks the data in an IDTSBuffer100 object.
Assembly: Microsoft.SqlServer.DTSPipelineWrap (in Microsoft.SqlServer.DTSPipelineWrap.dll)
This method is called when a data flow component has finished reading or writing data in the IDTSBuffer100. In low memory situations, the IDTSBufferManager100 may swap unlocked buffers from memory to disk.
Managed component developers do not need to call this method because the managed PipelineBuffer object automatically locks and unlocks itself.
