Function Documentation

◆ DATA_DummyFunction()

void DATA_DummyFunction ( void )

Dummy void function of the database module.

This function is needed in the database module in order to implement the DATA_READ_DATA() and DATA_WRITE_DATA() in a ISO C99 standard compatible way. The invocation of a macro that accepts a variable number of arguments (and this is the case for DATA_READ_DATA() and DATA_WRITE_DATA()) needs more arguments in the invocation than there are parameters in the macro definition. For the most simple case, that DATA_READ_DATA() and DATA_WRITE_DATA() are only called with one argument, a violation of the standard would appear if the DATA_DummyFunction() would be omitted: GET_MACRO(databaseVariable, DATA_Read4DataBlocks, DATA_Read3DataBlocks, DATA_Read2DataBlocks, DATA_Read2DataBlocks, DATA_Read1DataBlock)(databaseVariable) So the macro invocation has six parameters, but it needs seven and an ISO C99 violation would appear. Adding the DATA_DummyFunction() fixes this violation. For details see 6.10.3 (paragraph 4) of the ISO C99 standard.
