SYNOPSIS
package require Tcl 8.6 9
package require tcl::transform::core ?1.1?
package require tcl::transform::limitsize ?1.1?
::tcl::transform::limitsize chan max
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.
