| * Name: valloc |
| * |
| * Description: |
| * valloc - page-aligned memory allocator (OBSOLETE/LEGACY) |
| * |
| * valloc has the same effect as malloc(), except that the allocated |
| * memory is aligned to a page boundary. |
| * |
| * Input Parameters: |
| * size - Specifies the size (in bytes) of the allocated block of memory. |
| * If size is zero, a unique pointer to the heap is returned. |
| * |
| * Returned Value: |
| * The address of the allocated memory (NULL on failure to allocate) |
| * |
