NAME¶
tcl::transform::limitsize - limiting input
SYNOPSIS¶
package require
Tcl 8.6
package require
tcl::transform::core ?1?
package require
tcl::transform::limitsize ?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.
