## Determine The Number Of Foreign Key Constraint Violations

>     int sqlite3changeset_fk_conflicts(
>       sqlite3_changeset_iter *pIter,  /* Changeset iterator */
>       int *pnOut                      /* OUT: Number of FK violations */
>     );

This function may only be called with an iterator passed to an SQLITE_CHANGESET_FOREIGN_KEY conflict handler callback. In this case it sets the output variable to the total number of known foreign key violations in the destination database and returns SQLITE_OK.

In all other cases this function returns SQLITE_MISUSE.
