Functions ¶
func Copy ¶
Copy will copy from src to dst but ensures that writes are always of block size (bs) except for possibly the last write. Writes are not attempted until the high water mark (hwm) number of blocks are first read. At which point the buffer is written until empty. Then it waits until the high water mark is achieved again. The maximum buffer size is `n` blocks.
