Function Description
sint32 ydatad_init_datapool (const T_DBUS_Util *const opt_DBusInstance, charn * const
opcn_Datapool)
The function initializes the data pool ocn_Datapool. Before initializing the data pool, all lists within the data pool
have to be initialized. After initialization, it isn't possible to add more lists to the initialized data pool. The ydata
daemon creates a file in the named data pool subdirectory with the extension ".dpi". This file contains the
information about the created data pool.
