Description

set_operator_timeoutset_operator_timeoutSetOperatorTimeoutSetOperatorTimeoutSetOperatorTimeoutset_operator_timeout sets a timeout for the operator OperatorNameOperatorNameOperatorNameOperatorNameoperatorNameoperator_name. TimeoutTimeoutTimeoutTimeouttimeouttimeout is given in seconds. Setting TimeoutTimeoutTimeoutTimeouttimeouttimeout to 0 or 'off'"off""off""off""off""off" clears the timeout. The timeout is set for the current thread only and is not inherited by child threads.

Multiple operator names can be passed to OperatorNameOperatorNameOperatorNameOperatorNameoperatorNameoperator_name. In this case, one can either pass a single timeout in TimeoutTimeoutTimeoutTimeouttimeouttimeout, which is then set for all operators, or one timeout per operator.

Two timeout modes are supported and selected with ModeModeModeModemodemode:

'cancel'

Cancels the execution of the operator after the timeout expires, raises the exception H_ERR_TIMEOUT (9400). All results computed by the operator are discarded.

'break'

Break the execution of the operator after the timeout expires. The operator returns normally. If possible, results computed by the operator up to the point of the timeout are returned.

Attention

Note that not all operators support timeouts. If a given operator supports timeouts and which modes are supported is described in the execution information section of the reference documentation of the corresponding operator.

Also note that there is no hard guarantee about the granularity of the timeout. The granularity can depend on the operator, its input data and the speed of the device. It is typically finer than 10 ms.

Result

The operator set_operator_timeoutset_operator_timeoutSetOperatorTimeoutSetOperatorTimeoutSetOperatorTimeoutset_operator_timeout returns the value 2 (H_MSG_TRUE) if the parameters are correct. Otherwise an exception will be raised.
