Creating an empty object
You can create an XBSA object without any associated data. This is created in much the same way as an object with data with two differences. The estimatedSize.left and estimatedSize.right fields need to be zero so that the NetBackup XBSA interface knows that the object is going to be empty. After the BSACreateObject() call, the XBSA application calls BSAEndData() to end the object. If estimatedSize is set to zero and BSASendData() is called, this results in an error.
