DESCRIPTION

       The tcl::transform::limitsize package provides a command creating a channel transformation
       which limits the number of characters which can be read from the channel. A generator  for
       an artificial EOF.

       The  internal  TclOO  class  implementing  the  transform  handler  is  a sub-class of the
       tcl::transform::core framework.

API

       ::tcl::transform::limitsize chan max
              This command creates a size limiting transformation on top of the channel chan  and
              returns its handle.

              max  is  the  number  of  bytes  which  can  be read from the channel before EOF is
              signaled by the transformation. Note that popping the transformation clears the EOF
              it generated as well.
