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.
