The following examples show how the feature can be used. void foo(int arr [static 10]); /* arr points to the first of at least 10 ints */ void foo(int arr [const 10]); /* arr is a const pointer */ void foo(int arr [static const i]); /* arr points to at least i int...
is true for multimaps. The P_HASCATEGORY field can only be declared for the whole pblock. That means, that every multimap has to have the category parameter. To use the standard value ROLLUP_CAT_STANDARD can be used. In the example below 4900 is used as the integer describing the ...
