Share open files

All UDRs that execute under the same connection can share a file (because they have the same connection descriptor).

For example, if UDR1 opens a file, UDR2 can read, write to, or close this file, as long as these two UDRs execute under the same connection. However, UDRs that do not execute under the same connection cannot share a file.

The DataBlade API generates an error if your UDR attempts any of the following file I/O tasks:

To access a file that a UDR outside the session opened
To access a file that was not opened at all
To access a file that was opened and was closed
