Just out of curiosity, what are > you using crc32_combine and adler32_combile for? I have a process that feeds me checksums and chunks of data, but those chunks are getting buffered to be sent later (without the previously mentioned process's knowledge). Since the data is getting buffered, the checksum must be recalculated. Since my process has access to the checksums and length, it's easier to use crc32_combine rather than recalculate the checksums for each string (again). -- Aaron Patterson http://tenderlovemaking.com/
