A db++ server will prepare a TCL interpreter for each client connection. This interpreter
will enable the server to execute TCL code provided by the client as a sort of stored procedures to
improve the performance of database operations by avoiding client/server data transfers and context
switches.
dbplus_tcl() needs to pass the client connection id the TCL script
code should be executed by. dbplus_resolve() will
provide this connection id. The function will return whatever the TCL code returns or a TCL error
message if the TCL code fails.
