Thread: how could I connect a Postgres database in c language using odbc?

For connecting a DB (Oracle in this case) in JDBC I know the follow
java instructions:

    Class.forName("oracle.jdbc.driver.OracleDriver");
    String dbUrl =  "jdbc:oracle:thin:@"+host+":"+port+":"+sid;
    Connection m_connection = DriverManager.getConnection(dbUrl, user,
passwd);
    Statement m_statement = m_connection.createStatement();

Now, I'd like to know the equivalent instructions in c language using
ODBC for connecting a Postgres database.

Please, could anyone help me and tell me which these instructions are?

Thanks and bye,
