+ *                  pages[j] * counts[(i * npages) +  j]);
+ *       }
+ *   }
+ *
+ *   This little code snippet will produce something like this:
+ * Cell 0
+ *    Page size=4096 count=300 bytes=1228800
+ *    Page size=2097152 count=0 bytes=0

- *
- * This calls queries the host system on free pages of

- * unit is kibibytes, so e.g. pass 2048 for 2MB), then @startcell
- * refers to the first NUMA node that info should be collected

- * be queried. On the function output, @counts is filled with
- * desired information, where items are grouped by NUMA node.
- * So from @counts[0] till @counts[@npages - 1] you'll find count

- * till @count[2 * @npages - 1] you'll find info for the
- * (@startcell + 1) node, and so on. It's callers responsibility

- *
- * Example how to use this API:
- *
- *   unsigned int pages[] = { 4, 2048, 1048576}
- *   unsigned int npages = ARRAY_CARDINALITY(pages);
- *   int startcell = 0;

- *
- *   virNodeGetFreePages(conn, pages, npages,
- *                       startcell, cellcount, counts, 0);
- *
- *   for (i = 0 ; i < cellcount ; i++) {
- *       fprintf(stdout, "Cell %d\n", startcell + i);
- *       for (j = 0 ; j < npages ; j++) {
- *          fprintf(stdout, "  Page size=%d count=%d bytes=%llu\n",
- *                  pages[j], counts[(i * npages) +  j],
- *                  pages[j] * counts[(i * npages) +  j]);
- *       }
- *   }
- *
- *   This little code snippet will produce something like this:
- * Cell 0
- *    Page size=4096 count=300 bytes=1228800
- *    Page size=2097152 count=0 bytes=0
- *    Page size=1073741824 count=1 bytes=1073741824
- * Cell 1
- *    Page size=4096 count=0 bytes=0
- *    Page size=2097152 count=20 bytes=41943040
- *    Page size=1073741824 count=0 bytes=0
- *
- * Returns: the number of entries filled in @counts or -1 in case of error.
