Hi Glenn, > Sorry, the platforms are x86 Linux and sparc Sun Solaris (with gcc 3.2). Sun SPARC Solaris ... oh oh!

Compiled with gcc instead of g++, yes. An extern "C" function in C++ code... not sure. I think that will work in GCC's g++, but may not work with other C++ compilers. Perhaps needs a compiler flag to enable. HTH, --Eljay
