Concatenate Two Changeset Objects

int sqlite3changeset_concat(   int nA,                         /* Number of bytes in buffer pA */   void *pA,                       /* Pointer to buffer containing changeset A */   int nB,                         /* Number of bytes in buffer pB */   void *pB,                       /* Pointer to buffer containing changeset B */   int *pnOut,                     /* OUT: Number of bytes in output changeset */   void **ppOut                    /* OUT: Buffer containing output changeset */ );

This function is used to concatenate two changesets, A and B, into a single changeset. The result is a changeset equivalent to applying changeset A followed by changeset B.

This function combines the two input changesets using an sqlite3_changegroup object. Calling it produces similar results as the following code fragment:

   sqlite3_changegroup *pGrp;   rc = sqlite3_changegroup_new(&pGrp);   if( rc==SQLITE_OK ) rc = sqlite3changegroup_add(pGrp, nA, pA);   if( rc==SQLITE_OK ) rc = sqlite3changegroup_add(pGrp, nB, pB);   if( rc==SQLITE_OK ){     rc = sqlite3changegroup_output(pGrp, pnOut, ppOut);   }else{     *ppOut = 0;     *pnOut = 0;   }

Refer to the sqlite3_changegroup documentation below for details.
