/// \ingroup RAKNET_RPC
/// Register a C or static member function as available for calling as a remote procedure call
/// \param[in] uniqueID A null-terminated unique string to identify this procedure. See RegisterClassMemberRPC() for class member functions.
/// \param[in] functionPointer(...) The name of the function to be used as a function pointer. This can be called whether active or not, and registered functions stay registered unless unregistered
/// Register a C++ member function as available for calling as a remote procedure call.
/// \param[in] uniqueID A null terminated string to identify this procedure. Recommended you use the macro REGISTER_CLASS_MEMBER_RPC to create the string. Use RegisterAsRemoteProcedureCall() for static functions.
/// \param[in] functionPointer The name of the function to be used as a function pointer. This can be called whether active or not, and registered functions stay registered unless unregistered with UnregisterAsRemoteProcedureCall
/// Unregisters a C function as available for calling as a remote procedure call that was formerly registered with RegisterAsRemoteProcedureCall. Only call offline.
/// \param[in] uniqueID A string of only letters to identify this procedure. Recommended you use the macro CLASS_MEMBER_ID for class member functions.
