• doquery. Executes the supplied query.

• fetch. Retrieves the results from the back end.

• disconnectdb. Closes the database connection.

The following functions are provided by libpgeasy to accomplish the preceding:

• PGconn *connectdb(char *options);

• PGresult *doquery(char *query);

• int fetch(void *param);

• int fetchwithnulls(void *param);

• void reset_fetch();

• void disconnectdb();
