NFSv4 specifies that the RPC calls be batched into a "compound" call. There is no support for this in RPCGEN. By rearranging the ONC IDL for NFSv4 into AutoGen definitions, these templates will emit the original IDL *plus* all the code to package, send, distribute, collect, return, and dispatch the results. The distributed program author merely needs to call and supply server procedures for the routines specified in the IDL. Templates for these calls and service routines is provided, too. The NFSv4 definitions are included.
GNU ccScript offers a class extensible threaded embedded scripting engine for use with the Common C++ GNU package. This engine is also used in Bayonne (the GNU telephony server), and in TOSI (FreeBSD and GNU/Linux PBX integration servers). This engine differs from traditional scripting systems in that it is used to script near real-time state-event systems through deterministic callback step execution rather than the linear and non-deterministic fashion of embedded script libraries such as tcl, and libguile.
CwMtx is a library written in C++ that provides the matrix and vector operations that are used extensively in engineering and science problems. A special feature of this library is the quaternion class which implements quaternion math. Quaternions are very useful for attitude determination in 3D space because they do not suffer from singularities. Furthermore, successive rotations and transformations of vectors can be accomplished by simple quaternion multiplication. Attitude dynamics can be expressed in a very compact form using quaternions
FOX is a C++-based toolkit for GUI development. It includes a rich set of widgets and has powerful yet simple layout managers, MDI widgets, and mega-widgets. FOX incorporates support for XDND for drag and drop, X clipboard and X Selection, watching other I/O channels and sockets, timers and idle processing, object serialization and deserialization, a registry to save persistent settings, and 3D widgets using Mesa or OpenGL. FOX works on Linux, IRIX, Solaris, HP/UX, AIX, Tru64 Unix, Windows 9x,NT,2K (VC++, GNUWIN32, Borland, VisualAge C++), FreeBSD, and Sequent.
Boost was begun by members of the C++ standards committee Library Working Group to provide free peer-reviewed portable libraries to the C++ community. An additional objective is to establish "existing practice" and provide reference implementations so that the Boost libraries are suitable for eventual standardization. Indeed, the explicit intent is to propose many of these libraries for inclusion in the C++ Standard Library. The Boost Graph Library, formerly known as the Generic Graph Component Library (GGCL), is a collection of graph algorithms and data structures created in the generic programming style of the Standard Template Library (STL).
