In each loop before calling read() the buffer size is recalculated based on the amount of space used, causing a realloc *regardless* of how much empty space is left in the buffer.  And each read is only producing a smallish chunk (5120 bytes).

So assuming realloc fails to do an inplace realloc (and Windows is reputedly very bad at that) the amount of data copied will be O(n^2).
