mco_disk_flush

Explicitly flush the file system buffers.

Prototype

 
    MCO_RET	mco_disk_flush(	/*IN*/ mco_db_h db );
 

Arguments

db The database handle that was established by mco_db_connect()

Description

This function allows applications to explicitly flush the file system buffers; it is most often used in conjunction with the MCO_COMMIT_NOSYNC Transaction Commit policy.

Return Codes

MCO_S_OK File system buffers successfully flushed to disk. (No flush actually occurs if called for a in-memory database.)
MCO_E_DISK_FLUSH

Error flushing buffers to disk

MCO_E_DISK_OPERATION_NOT_ALLOWED An attempt was made to flush to disk with an active transaction open. This function must be called when the current connection has no active transactions

Example

 
    Application snippet:
        
     
    const char * dbname = "SimpleDb";
     
    int main(int argc, char* argv[])
    {
        mco_db_h db;
        MCO_RET rc;
        mco_device_t       dev[4];
        mco_db_params_t    db_params;
                 
        ...
        rc = mco_db_open_dev( dbname, simple_get_dictionary(), dev, 4, &db_params );
             
        if ( MCO_S_OK != rc )
        {
            rc = mco_db_connect(  dbname, &db );
            ...
            rc = mco_disk_flush( db );
        
            ...
        }
    }
