Description

This command provides facilities for manipulating binary data. The first form, binary format, creates a binary string from normal Tcl values. For example, given the values 16 and 22, it might produce an 8-byte binary string consisting of two 4-byte integers, one for each of the numbers. The second form of the command, binary scan, does the opposite: it extracts data from a binary string and returns it as ordinary Tcl string values.

See the binary(n) man page for more information.
