示例1: _append_recno_intercept
//static
int Db::_append_recno_intercept(DB *db, DBT *data, db_recno_t recno)
{
int err;
if (db == 0) {
DB_ERROR("Db::append_recno_callback", EINVAL, ON_ERROR_UNKNOWN);
return (EINVAL);
}
Db *cxxdb = (Db *)db->cj_internal;
if (cxxdb == 0) {
DB_ERROR("Db::append_recno_callback", EINVAL, ON_ERROR_UNKNOWN);
return (EINVAL);
}
if (cxxdb->append_recno_callback_ == 0) {
DB_ERROR("Db::append_recno_callback", EINVAL, cxxdb->error_policy());
return (EINVAL);
}
// making these copies is slow but portable.
// Another alternative is to cast the DBT* manufactured
// by the C layer to a Dbt*. It 'should be' safe since
// Dbt is a thin shell over DBT, adding no extra data,
// but is nonportable, and could lead to errors if anything
// were added to the Dbt class.
//
Dbt cxxdbt;
memcpy((DBT *)&cxxdbt, data, sizeof(DBT));
err = (*cxxdb->append_recno_callback_)(cxxdb, &cxxdbt, recno);
memcpy(data, (DBT *)&cxxdbt, sizeof(DBT));
return (err);
}示例2: _feedback_intercept
//static
void Db::_feedback_intercept(DB *db, int opcode, int pct)
{
if (db == 0) {
DB_ERROR("Db::feedback_callback", EINVAL, ON_ERROR_UNKNOWN);
return;
}
Db *cxxdb = (Db *)db->cj_internal;
if (cxxdb == 0) {
DB_ERROR("Db::feedback_callback", EINVAL, ON_ERROR_UNKNOWN);
return;
}
if (cxxdb->feedback_callback_ == 0) {
DB_ERROR("Db::feedback_callback", EINVAL, cxxdb->error_policy());
return;
}
(*cxxdb->feedback_callback_)(cxxdb, opcode, pct);
