+/* Macros to create and fill 2D arrays with a single heap allocation.
+ * These can be used to replace large stack and global arrays which raise
+ * warnings.
+ *
+ * The macros make a single heap allocation large enough to hold all the
+ * pointers and the data elements. The first part of the allocation holds
+ * the pointers, and the second part holds the data as a contiguous block
+ * in row-major order.
+ *
+ * To pass the data block to calls like H5Dread(), pass a pointer to the
+ * first array element as the data pointer (e.g., array[0] in a 2D array).
+ *
+ * The fill macro just fills the array with an increasing count value.
+ *
+ * Usage:
+ *
+ * int **array;
+ *
+ * H5TEST_ALLOCATE_2D_ARRAY(array, int, 5, 10);
+ *
+ * H5TEST_FILL_2D_ARRAY(array, int, 5, 10);
+ *
+ * (do stuff)
+ *
+ * HDfree(array);
