qdb_parameters()
Get or set database connection parameters
Synopsis:
#include <qdb/qdb.h> int qdb_parameters( qdb_hdl_t *db, int mask, int bits );
Arguments:
- db
- A pointer to the database handle.
- mask
- A bitmask representing the connection parameters you want to update. If you want to query the current connection parameters without modifying them, set this argument to 0.
- bits
- The bits corresponding to the parameters you want to enable. If a bit is in mask but not in bits, the parameter is unset (i.e., disabled).
Library:
qdbDescription:
This function queries or modifies the parameters for the specified database connection. You can set or unset the QDB_CONN_NONBLOCKING and QDB_CONN_STMT_ASYNC bits (see the flags argument for qdb_connect() for details about these settings). You can't change the QDB_CONN_DFLT_SHARE bit.
The function returns the previous bitmask (i.e., parameter settings), so the parameter settings can be temporarily changed and later restored.
Returns:
- >=0
- The previous value of the bitmask.
- -1
- An error occurred (errno is set).
