Detailed Description

Typedef Documentation

qdb_log_callback

A typedef representing a log callback.

An unique callback identifier returned by qdb_log_add_callback.

An enumeration of log level.

Enumerator
qdb_log_detailed	Log everything. Very verbose.
qdb_log_debug	Log debug level messages and below.
qdb_log_info	Log information level messages and below.
qdb_log_warning	Log warning level messages and below.
qdb_log_error	Log error level messages and below.
qdb_log_panic	Log panic level messages and below. Very terse.

QDB_API_LINKAGE qdb_error_t qdb_log_add_callback	(	qdb_log_callback	cb,
		qdb_log_callback_id *	callback_id
	)

Adds a callback that will receive internal API log messages. This can be used to incorporate internal API statuses in your log.

Parameters

cb	A callback of type qdb_log_callback. The callback will be called every time the API emits a log message.
callback_id	A pointer to an unique callback identifier that can be used to remove the callback.

QDB_API_LINKAGE int qdb_log_option_is_sync ( void )

Indicates if logs are synchronized for each API call (disabled by default).

Returns: 1 if logs are flushed before returning from each API call, 0 otherwise.

Warning: This function is still under development. Performance and compatibility are not guaranteed.

QDB_API_LINKAGE void qdb_log_option_set_sync ( int sync_logger )

Set logs to be synchronous for each API call (disabled by default).

Parameters

sync_logger 1 if logs must be flushed before returning from each API call, 0 otherwise.

Warning: This function is still under development. Performance and compatibility are not guaranteed.

QDB_API_LINKAGE qdb_error_t qdb_log_remove_callback ( qdb_log_callback_id callback_id )

Removes a previously added log callback.

Parameters

callback_id The identifier set by qdb_log_add_callback that will determine which callback to remove.
