Data Management functions

• The store_id method is used to store the identifier of persistent data. It also accepts a description of the data stored. This method has to be called after the diet_call() so that the identifier exists.

    store_id(char* argID,char *msg);
  

• The diet_use_data method allows the client to use a data item that is already stored in the platform.

    diet_use_data(diet_arg_t* arg,char* argID);
  

  This function replaces the set functions (see Section 3.4.1).

  NB:

  a mechanism for data identifier publication hasn't been implemented yet. So, exchanges of identifiers between end-users that want to share data must be done explicitly.

• The diet_free_persistent_data method allows the client to remove a persistent data item from the platform.

    diet_free_persistent_data(char *argID);
  

/*******************************************************************
 *   Add handler argID and text message msg in the identifier file *
 ******************************************************************/

void 
store_id(char* argID, char* msg);


/** sets only identifier : data is present inside the platform */

void
diet_use_data(diet_arg_t* arg, char* argID);


/******************************************************************
 *  Free persistent data identified by argID                     *
 *****************************************************************/
int
diet_free_persistent_data(char* argID);
