%X CCSP is a highly portable run\-time system that conforms to
   the ideas of CSP and supports both the C and occam
   programming languages. Its aim is to further the use of the
   CSP mind\-set in both industrial and academic applications.
   The run\-time system implements a useful and efficient
   subset of the basic CSP constructs. It allows occam\-style
   designs to be programmed in C, thereby allowing full use of
   the optimisation phases of standard C compilers. It supports
   the KRoC occam system for Linux/PC platforms. In addition, a
   number of features have emerged from industrial
   collaboration as essential for soft real\-time systems in
   the real world. These include: prioritised scheduling with
   32 priority levels, integration of communications hardware
   to provide support for distributed processing, and access to
   a highly accurate real\-time clock. This paper discusses the
   high level structure and functionality of the features
   provided.
