Reallocates collectable memory.


void * NSReallocateCollectable(void *ptr, NSUInteger size, NSUInteger options);


Changes the size of the block of memory pointed to by ptr to size bytes. It may allocate new memory to replace the old, in which case it moves the contents of the old memory block to the new block, up to a maximum of size bytes.

options can be 0 or NSScannedOption: A value of 0 allocates non-scanned memory; a value of NSScannedOption allocates scanned memory.

This function returns NULL if it’s unable to allocate the requested memory.
