### Prototype

        MCO_RET	mco_index_stat_num(	/*IN*/ mco_trans_h t,
                        /*IN*/ uint2 * n_indexes );

### Arguments

t | The `mco_trans_h` transaction handle returned by `mco_trans_start()`.
n_indexes | Address of a 2-byte unsigned integer representing the total number of indexes in the database.

### Description

> This function returns the number of indexes in the database.

### Return Codes

MCO_S_OK | The number of indexes was returned successfully.

### Example

        Application snippet:

        const char * dbname = "SimpleDb";

        int main(int argc, char* argv[])
        {
            mco_db_h db;
            MCO_RET rc;
            mco_device_t       dev;
            mco_db_params_t    db_params;
            mco_trans_h t;
            uint2 n_indexes;

            ...
            rc = mco_db_open_dev( dbname, simple_get_dictionary(), &dev, 1, &db_params );
            if ( MCO_S_OK != rc )
            {
                rc = mco_db_connect(  dbname, &db );
                ...
                rc = mco_trans_start(db, MCO_READ_ONLY, MCO_TRANS_FOREGROUND, &t);
                if ( MCO_S_OK == rc )
                {
                    rc = mco_index_stat_num( t, &n_indexes);

                    ...
                 }

            ...
            }
