Memory::Realloc

static void* SF_STDCALL Realloc(void * p, UPInt newSize);

Realloc reallocates the memory block allocated by Alloc to a new size. Reallocation to smaller size than that of the original allocation will never fail and a return of 0 would mean that the function can't reallocate on fail, and previous memory is still valid. 

Realloc of pointer == 0 is equivalent to Alloc and Realloc of newSize == 0 is equivalent to Free and will return 0. 

Note: Custom alignments are not possible with Realloc. If custom alignment is required, an Alloc/Free call should be made.
