qdb_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:

qdb

Description:

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).

Classification:

QNX Neutrino

Safety:
Interrupt handler	No
Signal handler	No
Thread	Yes
