Memchan

Memchan is an extension library to the script language Tcl, as created by John Ousterhout. It provides two new channel types for in-memory channels and the appropriate commands for their creation. They are useful to transfer large amounts of data between procedures or interpreters, and additionally provide an easy interface to on-the-fly generation of code too. No need to set or append to a string, just do a simple puts.

    Release Notes: Added support for TEA compliant building of this extension. This requires at least Tcl/Tk 8.2. The old built facilities (unix, win) still exist and are still usable. Also added an option to 'memchan', for preallocation of bufferspace, added option '-allocated' to 'fconfigure', to allow a user to query the number of bytes allocated by the buffers, in contrast to -length, which retrieves the number of used bytes.
