tcl::transform::crc32 - Crc32 transformation
- package require Tcl 8.6
- package require tcl::transform::core ?1?
- package require tcl::transform::crc32 ?1?
The tcl::transform::crc32 package provides a command creating a channel transformation which passes the read and written bytes through unchanged (like tcl::transform::identity), but additionally continuously computes the crc32 checksums of the data it has seen for each direction and stores them in Tcl variables specified at construction time. The checksum in question is zlib's crc32.
- ::tcl::transform::crc32 chan -option value...
This command creates a crc32 checksumming transformation on top of the channel chan and returns its handle. The accepted options are
