1 This extension provides a Tcl interface to the mmap(2) POSIX system
4 It provides a Tcl package that allows Tcl scripts to:
5 1) Memory map files for improved access efficiency;
6 2) Share memory between related processes;
7 3) Easily implement cyclic persistent log files.
9 The functionality of 'mmap' is exported from this extension in the
10 form of a new Tcl channel type, named "mmap". A memory mapping is
11 established with the 'mmap' command. Following 'mmap' execution,
12 access to the memory mapped file is done via the standard Tcl
13 commands: puts/gets/seek/flush/close/fconfigure, only that this
14 time these commands operate on memory, rather than on a file.
