The Berkeley DB Tcl API does not attempt to avoid evaluating input as Tcl -commands. For this reason, it may be dangerous to pass unreviewed user -input through the Berkeley DB Tcl API, as the input may subsequently be -evaluated as a Tcl command. Additionally, the Berkeley DB Tcl API -initialization routine resets process' effective user and group IDs to -the real user and group IDs, to minimize the effectiveness of a Tcl -injection attack.

-

The Tcl API closely parallels the Berkeley DB programmatic interfaces. If you -are already familiar with one of those interfaces, there will not be many -surprises in the Tcl API.

-

The Tcl API currently does not support multithreading although -it could be made to do so. The Tcl shell itself is -not multithreaded and the Berkeley DB extensions use global data unprotected -from multiple threads.

-

Several pieces of Berkeley DB functionality are not available in the Tcl API. -Any of the functions that require a user-provided function are not -supported via the Tcl API. For example, there is no equivalent to the -DB->set_dup_compare() or DB_ENV->set_errcall() methods. -Additionally, the heap access method is not available.
