NAME¶
tcl::chan::variable - In-memory channel using variable for storage
SYNOPSIS¶
package require
Tcl 8.5
package require
TclOO
package require
tcl::chan::events ?1?
package require
tcl::chan::variable ?1?
::tcl::chan::variable varname
DESCRIPTION¶
The
tcl::chan::variable package provides a command creating channels
which live purely in memory. They provide random-access, i.e. are seekable. In
contrast to the channels created by
tcl::chan::memchan the data is not
hidden in the channel however, but stored in an associated variable, specified
at the time of construction.
Packages related to this are
tcl::chan::memchan and
tcl::chan::string.
The internal
TclOO class implementing the channel handler is a sub-class
of the
tcl::chan::events framework.
API¶
- ::tcl::chan::variable varname
- This command creates a new variable channel and returns its handle. The
content of the channel is stored in the associated namespace variable
varname.
