These binary -cursors can not be used if you are running the -.BR pgeasy -client on a system with a different architecture than the database -server. If you pass a NULL pointer parameter, the column is skipped. -.BR fetchwithnulls -allows you to retieve the -.IR null -status of the field by passing an -.IR int* -after each result pointer, which returns true or false if the field is null. -You can always use libpq functions on the PGresult pointer returned by -.BR doquery . -.BR reset_fetch -starts the fetch back at the beginning. -.PP -.BR get_result , -.BR set_result , -and -.BR unset_result -allow you to handle multiple result sets at the same time. -.PP -There are a variety of demonstration programs in the -.BR pgeasy -source directory. |
