DEFINITION MODULE SQLiteUtils ;

(*
   m2SQLITE - small pure-Modula-2 helpers over the FOR "C" SQLite
   binding. CStrToM2 copies NUL-terminated C strings (ADDRESS)
   into Modula-2 CHAR arrays (NUL-terminated, truncated to fit).
   StaticDestr/TransientDestr return the SQLITE_STATIC and
   SQLITE_TRANSIENT destructor sentinels; BindTextCopy/BindBlobCopy
   bind with SQLITE_TRANSIENT so SQLite copies the value.
