NAME

sqlite3changeset_concat — concatenate two changeset objects

SYNOPSIS

#include <sqlite3.h>

int
sqlite3changeset_concat(int nA, void *pA, int nB, void *pB, int *pnOut, void **ppOut);

DESCRIPTION

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.
