Dear Mikko,
QNX and SOftintegration teamed up to provide C/C++ interpreter
Ch for QNX users.
We think that many readers of your journals might be
interested in this news. Attached please find our company press
release for possible coverage or review in your journal.
Feel free to use the logo of our company and products
from the following link

QNX, SoftIntegration Team Up to Provide C/C++ Scripting Technology
DAVIS, California, January 10, 2005 - SoftIntegration, Inc. today
announced the availability of Ch Standard Edition 4.7, Ch SDK 4.7, and
Embedded Ch 4.7 for the QNX Neutrino RTOS. Ch is an embeddable C/C++
interpreter for cross-platform scripting, 2D/3D plotting, numerical
computing, shell programming, and embedded scripting. Extending its success
in Windows, Unix and MacOS X, SoftIntegration now allows QNX developers
to use C/C++ for scripting, shell programming, and embedded scripting.
SoftIntegration provides software developers with a robust C/C++
interpreter, compatible with C99 and C++ class.
"Many of SoftIntegration's customers have already requested Ch for the
QNX Neutrino RTOS. We recognize that QNX Neutrino is one of leading realtime
operating systems in the embedded industry, and we are pleased to provide
a powerful C/C++ interpreter for QNX users," said Dr. Dawn Cheng,
president of SoftIntegration.
"We are pleased that SoftIntegration is now offering both Ch and Embedded
Ch to the QNX development community," added Linda Campbell, director of
strategic alliances, QNX Software Systems. "These solutions complement
the rich suite of C/C++ tools offered by the QNX Momentics development
suite and allow QNX developers to apply their existing C/C++ skills to
a greater variety of programming tasks"
Below is a list of major Ch features:
* C/C++ interpreter
Ch supports 1999 ISO C Standard (C99) and C++ classes. Ch also
supports many industry standards with over 8,000 functions, including
POSIX, socket/Winsock, X11/Motif, OpenGL, ODBC, C LAPACK, GTK+, Win32,
and CGI. Functions in static or dynamic binary C/C++ libraries can be
executed interpretively in scripting without re-compilation using Ch SDK.
* Shell programming and cross-platform scripting
Ch shell is C compatible shell while C-shell (csh) is a C like shell.
Ch is an interpretive implementation of C, similar to Unix/MS-DOS shells.
Ch in Windows includes over 100 commonly used Unix commands for portable
shell programming. Ch can also be used as a login shell just like sh, csh
and ksh. Ch bridges the gap between the C language and shell languages.
With its built-in string type and many enhanced scripting features, Ch is
an alternative to other scripting languages for automating repetitive
tasks, regression test, and hardware testing with direct interface to
hardware.
* Interface with binary C/C++ libraries
Ch SDK 4.7 can easily integrate existing C/C++ libraries as part of
Ch scripting modules. Functions and classes in static or dynamic libraries
can be invoked in a Ch script file or Ch command shell.
* Embeddable scripting
Ch 4.7 is optimized for embedded scripting. Embedded Ch allows users
to embed Ch into other C/C++ application programs and hardware. It is
ideal for open-architecture application integration. With Embedded Ch,
C/C++ applications can be extended with all features of Ch. It allows
execution of C/C++ scripts generated dynamically on-line. Embedded Ch has a
small footprint. The pointer and time deterministic nature of the C language
provides a perfect interface with hardware in realtime systems.
* Ch toolkits and third party software support
Ch supports an increasing number of third party software applications.
It includes Ch Control toolkit, Ch Mechanism Toolkit, Ch NAG Statistics
Package, Ch CGI toolkit, Ch ODBC toolkit, Ch XML toolkit, Intel OpenCV for
computer vision and image processing, National Instruments' data acquisition
toolkit NI-DAQ and motion control toolkit NI-Motion, Barret Technology's
Barret Hand robotic manipulator control, and IDE.
Pricing and Availability
Ch Standard Edition is free for both commercial and non-commercial uses in
all platforms. Ch SDK costs $899. To purchase Embedded Ch, contact
SoftIntegration directly.
About SoftIntegration, Inc.
SoftIntegration, Inc., is the leader of scripting technology for ubiquitous
computing. SoftIntegration provides infrastructure software and services for
rapid application development and deployment, scientific numerical computing,
embedded scripting, and Web-based software integration. Ch, the company's
flagship product, is an embeddable C/C++ interpreter that provides a
comprehensive solution for engineers, scientists, Web programmers, software
developers, C/C++ beginners and experts, system administrators, realtime
programmers, quality analysts, and instructors and professors.

Subject: Vstr 1.0.14 (string library in C)
From: James Antill <james@and.org>
About
-----
Vstr is a string library, it's designed so you can work optimally with
readv()/writev() for input/output. This means that, for instance, you
can readv() data to the end of the string and writev() data from the
beginning of the string without having to allocate or move memory. It
also means that the library is completely happy with data that has
multiple zero bytes in it.
This design constraint means that unlike most string libraries Vstr
doesn't have an internal representation of the string where everything
can be accessed from a single (char *) pointer in C, the internal
representation is of multiple "blocks" or nodes each carrying some of
the data for the string. This model of representing the data also
means that as a string gets bigger the Vstr memory usage only goes up
linearly and has no inherent copying. It also means that the string
can do automatic referencing for mmap() areas of memory,
Other convenience functions are also included, so you can: easily
compare data, search for data and split data from a string into
sections (similar to perl's split function). In a POSIX environment
the short cut functions to call readv/writev are included.
It also includes a portable version of a printf-like function (which
is ISO 9899:1999 compliant, and includes support for i18n parameter
position modifiers). However, as well as being portable, there is a
large extension available called "custom formatters" which allows you
to print any type (Ie. ipv4 addresses or Vstr strings) via. the printf
like function (and this is done in such a way that static format
checkers like gcc will understand what is being done).
Main Changes
------------
. Some corner case bugs found in applications
Unit testing is still at 100% code coverage.
. In the vstr_sc_*file* functions use O_NONBLOCK on open() to stop
hangs on FIFOs, also repeat read() request until all file is read or
encounter an error.
. Encoded more characters in vstr_conv_encode_uri().
. The HTTPD example application is now (I believe) compliant with
HTTP/1.1. I believe it to be secure from remote attacks (although
that doesn't include DOS attacks). It also has code to stop response
splitting.
It should be very fast (uses epoll on Linux, can have one proc. per
CPU, and some other API tricks -- plus the Vstr library :).
It also has a feature to make gzip content-encoding very easy to use,
which can save a lot of bandwidth.
There is also a perl script to convert the log files to apache
combined format.
. Build fixes for non-Linux platforms.
