/**
* @brief This operation allows making the domain's network stack
* temporarily deaf and/or mute. It is a support function for testing and,
* other special uses and is subject to change.
*
* @param[in] entity A domain entity or an entity bound to a domain, such
* as a participant, reader or writer.
* @param[in] deaf Whether to network stack should pretend to be deaf and
* ignore any incoming packets.
* @param[in] mute Whether to network stack should pretend to be mute and
* discard any outgoing packets where it normally would.
* pass them to the operating system kernel for transmission.
* @param[in] reset_after Any value less than INFINITY will cause it to
* set deaf = mute = false after reset_after ns have passed.
* This is done by an event scheduled for the appropriate
* time and otherwise forgotten. These events are not
* affected by subsequent calls to this function.
*
* @returns A dds_return_t indicating success or failure.
*
* @retval DDS_RETCODE_OK
* The operation was successful.
* @retval DDS_BAD_PARAMETER
* The entity parameter is not a valid parameter.
* @retval DDS_RETCODE_ILLEGAL_OPERATION
* The operation is invoked on an inappropriate object.
