SQLITE3CHANGEGROUP_OUTPUT(3)                          Library Functions Manual

NAME
     sqlite3changegroup_output - obtain a composite changeset from a
     changegroup

SYNOPSIS
     #include <sqlite3.h>

     int
     sqlite3changegroup_output(sqlite3_changegroup*, int *pnData,
         void **ppData);

DESCRIPTION
     Obtain a buffer containing a changeset (or patchset) representing the
     current contents of the changegroup.  If the inputs to the changegroup
     were themselves changesets, the output is a changeset.  Or, if the inputs
     were patchsets, the output is also a patchset.

     As with the output of the sqlite3session_changeset() and
     sqlite3session_patchset() functions, all changes related to a single
     table are grouped together in the output of this function.  Tables appear
     in the same order as for the very first changeset added to the
     changegroup.  If the second or subsequent changesets added to the
     changegroup contain changes for tables that do not appear in the first
     changeset, they are appended onto the end of the output changeset, again
     in the order in which they are first encountered.

     If an error occurs, an SQLite error code is returned and the output
     variables (*pnData) and (*ppData) are set to 0.  Otherwise, SQLITE_OK is
     returned and the output variables are set to the size of and a pointer to
     the output buffer, respectively.  In this case it is the responsibility
     of the caller to eventually free the buffer using a call to
     sqlite3_free().
