* 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)
*
