Each map can hold only one type of data; int64, string, or statistics. Each element belonging to a map can have up to 2 keys and a value. Implemented key types are strings and longs.<p> To simplify the implementation, the functions to set the key and the functions to set the data are separated. That means we need only 4 functions to set the key and 3 functions to set the value.<p> For example: <div class="fragment"><pre class="fragment"> <span class="comment">/* create a map with a max of 100 elements */</span> @@ -28,7 +28,7 @@ map_set_int64 (mymap, 2000); </pre></div><p> All elements have a default value of 0 (or NULL).
