     sqlite3changegroup_new - Create A New Changegroup Object

     sqlite3changegroup_new(sqlite3_changegroup **pp);

     An sqlite3_changegroup object is used to combine two or more changesets
     (or patchsets) into a single changeset (or patchset).  A single
     changegroup object may combine changesets or patchsets, but not both.
     The output is always in the same format as the input.

     If successful, this function returns SQLITE_OK and populates (*pp) with a
     pointer to a new sqlite3_changegroup object before returning.  The caller
     should eventually free the returned object using a call to
     sqlite3changegroup_delete().  If an error occurs, an SQLite error code
     (i.e.  SQLITE_NOMEM) is returned and *pp is set to NULL.

     The usual usage pattern for an sqlite3_changegroup object is as follows:

        It is created using a call to sqlite3changegroup_new().

        Zero or more changesets (or patchsets) are added to the object by
         calling sqlite3changegroup_add().

        The result of combining all input changesets together is obtained by
         the application via a call to sqlite3changegroup_output().

        The object is deleted using a call to sqlite3changegroup_delete().

     Any number of calls to add() and output() may be made between the calls
     to new() and delete(), and in any order.

     As well as the regular sqlite3changegroup_add() and
     sqlite3changegroup_output() functions, also available are the streaming
     versions sqlite3changegroup_add_strm() and
