Obtain an LO file descriptor

The smart-large-object creation functions return an LO file descriptor for a smart large object. The LO file descriptor is needed for most subsequent operations on the smart large object. However, this LO file descriptor is only valid within the current database connection.

For a list of smart-large-object functions, see Smart-large-object creation functions.
