ToC path:

mco_uda_db_open

Open the database for UDA.

Prototype

 
    MCO_RET mco_uda_db_open(	/*IN*/const mco_metadict_header_t * metadict, 
                  /*IN*/ unsigned short dict_no,
                  /*IN*/ mco_device_t * devs, 
                  /*IN*/ mco_size_t n_devs,
                  /*IN*/ mco_db_params_t * params);

Arguments

metadict	The address of an initialized mco_metadict_header_t structure
dict_no	The number of the dictionary (must be between 0 and `mco_metadict_count()` - 1)
devs	An array containing at least one initialized memory device structures
n_devs	The number of memory device structures
params	Initialized database parameters structure

Description

This function can be used to replace mco_db_open_dev().

Return Codes

MCO_S_OK	The database was successfully opened
MCO_E_UDA_DICT_NOTFOUND	The dictionary is not registered
MCO_E_UDA_DICT_NOT_DIRECT	The dictionary has not been registered explicitly

Example

 
    Application snippet:
        
     
    const char * dbname = "SimpleDb";
     
    int main(int argc, char* argv[])
    {
        MCO_RET rc;
        mco_runtime_info_t info;
        unsigned int dict_no = 0;
        unsigned int count;
        mco_metadict_header_t *header;
        mco_device_t       dev;
        unsigned int n_dev;
        mco_db_params_t db_params;

        ...
        mco_runtime_start();
        mco_get_runtime_info(&info);
        ...
         
        header = (mco_metadict_header_t *) malloc(size);
        mco_metadict_init(header, size); /* initialize the metadict */
        ...
         
        /* open database */
        rc = mco_uda_db_open(metadict,   /* meta-dictionary header - must be initialized */
                     0,             /* dictionary number */
                    dev,            /* memory devices */
                    n_dev,          /* num of memory devices */
                    &db_params); /* db parameters */
        ...
    }
