If you want to do this, publish an interface in your C++ library with the interface functions declared as extern "C" > 2) C++ based function, calling a C++ library (I read in the > pgsql docs > that compiling C++ code for use with pgsql is either partially > incompatible, or just a bad idea?) C++ calling C++ is not portable because of name mangling. Other than that, if you use the same compiler there is rarely any problem. > Also note that I would like to pass the function the > following arguments: int4, _varchar (array of varchars) > > Any help would be appreciated, I'm not incredibly experienced > in these > matters. I would use an extern "C" interface, if I were in your shoes. ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
