Returns the value of the field specified by "pos" in the current row. All values except binary objects are returned as \0 terminated strings. Numbers have to be converted to their binary representation before arithmetic operations are allowed. The value of "pos" must be in the range from 0 to odbx_column_count()-1. A value of NULL is both, a valid field value and the return value in case of an error, but errors only occur if "pos" is outside the valid range or "handle" is invalid.
