Settings for event.
In a DDS::DomainParticipant, a thread is dedicated to handle all timed events, including checking for timeouts and deadlines and executing internal and user-defined timeout or exception handling routines/callbacks.
This QoS policy allows you to configure thread properties such as priority level and stack size. You can also configure the maximum number of events that can be posted to the event thread. By default, a DDS::DomainParticipant will dynamically allocate memory as needed for events posted to the event thread. However, by setting a maximum value or setting the initial and maximum value to be the same, you can either bound the amount of memory allocated for the event thread or prevent a DDS::DomainParticipant from dynamically allocating memory for the event thread after initialization.
This QoS policy is an extension to the DDS standard.
ThreadSettings_t ^ DDS::EventQosPolicy::thread |
Event thread QoS.
There is only one event thread.
Priority:
[default] The actual value depends on your architecture:
For Windows: -2
For Linux: OS default priority
For a complete list of platform specific values, please refer to Platform Notes.
Stack Size:
[default] The actual value depends on your architecture:
For Windows: OS default stack size
For Linux: OS default stack size

Mask:
[default] mask = DDS::ThreadSettingsKind::THREAD_SETTINGS_FLOATING_POINT | DDS::ThreadSettingsKind::THREAD_SETTINGS_STDIO
System::Int32 DDS::EventQosPolicy::initial_count |
The initial number of events.
[default] 256
[range] [1, 1 million], <= max_count
System::Int32 DDS::EventQosPolicy::max_count |
The maximum number of events.
The maximum number of events. If the limit is reached, no new event can be added.
[default] DDS::ResourceLimitsQosPolicy::LENGTH_UNLIMITED
[range] [1, 1 million] or DDS::ResourceLimitsQosPolicy::LENGTH_UNLIMITED, >= initial_count
