119  * @brief Dummy void function of the database module
120  * @details This function is needed in the database module in order to
121  * implement the #DATA_READ_DATA() and #DATA_WRITE_DATA() in a ISO C99
122  * standard compatible way. The invocation of a macro that accepts a
123  * variable number of arguments (and this is the case for
124  * #DATA_READ_DATA() and #DATA_WRITE_DATA()) needs more arguments in the
125  * invocation than there are parameters in the macro definition. For
126  * the most simple case, that #DATA_READ_DATA() and #DATA_WRITE_DATA() are
127  * only called with one argument, a violation of the standard would
128  * appear if the #DATA_DummyFunction() would be omitted:
129  * GET_MACRO(databaseVaribale,
130  * DATA_Read_4_DataBlocks,
131  * DATA_Read_3_DataBlocks,
132  * DATA_Read_2_DataBlocks,
133  * DATA_Read_2_DataBlocks,
134  * DATA_Read_1_DataBlock)(databaseVaribale)
135  * So the macro invocation has six parameters, but it needs seven and
136  * an ISO C99 violation would appear. Adding the #DATA_DummyFunction()
137  * fixes this violation.
138  * For details see 6.10.3 (paragraph 4) of the ISO C99 standard.
