Changes to src/sqlite.h.in.

   706    706   ** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
   707    707   ** extends and truncates the database file in chunks of a size specified
   708    708   ** by the user. The fourth argument to [sqlite3_file_control()] should 
   709    709   ** point to an integer (type int) containing the new chunk-size to use
   710    710   ** for the nominated database. Allocating database file space in large
   711    711   ** chunks (say 1MB at a time), may reduce file-system fragmentation and
   712    712   ** improve performance on some systems.
          713  +**
          714  +** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
          715  +** to the [sqlite3_file] object associated with a particular database
          716  +** connection.  See the [sqlite3_file_control()] documentation for
          717  +** additional information.
