block-stream
A stream of blocks.
Write data into it, and it’ll output data in buffer blocks the size you specify, padding with zeroes if necessary.
var block = new BlockStream(512)
.createReadStream("some-file").pipe(block)
fs.pipe(fs.createWriteStream("block-file")) block
When .end()
or .flush()
is called, it’ll
pad the block with zeroes.
