<body class='hmmessage'><div dir='ltr'>Hello,<br><br> I want to create a C++ program to access the vector data in Grass. I use Vect_open_old to open the table and Vect_read_line to access the geometrical data. However, I don't know how to access to the column data. Should I use GRASS DataBase Management Interface? Any example code? <br><br>Thanks in advance<br> </div></body>
