OKay, I will add some document and test about adler32 and crc32 :-)
the adler32 and crc32 only return numbers (uint32_t), but most of times we need read/write the checksum from file, and check. that why I add tobinary. maybe I should add some read/writeint32 or just the idea belongs you: remove it from zlib, and use lpack instead.
I will use the second way :)
