	Yes we are using esql with C++. We created the following include file 
	that resolves the C++ prototype errors:
 
extern "C"
{
     int rtypmsize (int, int);
     int rtypalign (int, int);
     void rsetnull (int, void *);
     int  risnull (int, void *);
     void _iqbeginwork( ... );
     void _iqcopen( ... );
     void _iqdatabase( ... );
     void _iqdclcur( ... );
     void _iqddclcur( ... );
     void _iqclose( ... );
     void _iqcommit( ... );
     void _iqdbclose( ... );
     void _iqfree( ... );
     void _iqnftch( ... );
     void _iqprepare( ... );
     void _iqstmnt( ... );
     void _iqdscribe( ... );
     void _iqslct( ... );
     void _iqxecute( ... );
}

	Hope this helps!
