Return Value
A pointer to the reallocated block is returned. The reallocated block may
be located at a different address than the original block. NULL is returned

Explanation
The previously allocated area of storage pointed to by block is reallocated
to the size specified by s. realloc() is identical to malloc()
if block is NULL.
