The file/bzip2 module provides support for compressing and decompressing data using the bzip2 file format.
procedure
( bzip2-input-port in)→input-port?
in:input-port?
procedure
out:output-port?block-size:(integer-in19)=9
The optional block-size parameter controls size of the internal buffer used for compression. In general, the larger the block size, the better the compression — but also the higher the memory use. To reduce memory use, choose a lower value for block-size.
