## Constants

| Constant   | Description                                                                                                                                                                                                                                      |
| ---------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| audio      | Represents Game Chat 2 internal audio threads.<br /><br /> Game Chat internal audio threads are high priority, frequently-running threads with real-time requirements. These threads interact directly with XAudio2 every 20 to 40 milliseconds. |
| networking | Represents Game Chat 2 internal networking threads.<br /><br /> Game Chat 2 internal networking threads are driven by polling mechanisms. These wake every 50 to 100 milliseconds.                                                               |

## Remarks

This enumeration is used by [chat\_manager::get\_thread\_processor](/reference/chat/gamechat2/classes/chat_manager/methods/chat_manager_get_thread_processor) and [chat\_manager::set\_thread\_processor](/reference/chat/gamechat2/classes/chat_manager/methods/chat_manager_set_thread_processor) to identify the Game Chat 2 internal thread type for which processor affinity is configured.

When calling `chat_manager::set_thread_processor` to configure the processor affinity for Game Chat 2 internal audio threads, XAudio2 instances for Game Chat 2 are initialized with a processor affinity that corresponds to the configured processor number. If no processor number is specified for this thread type, XAudio2 instances for Game Chat 2 are initialized with the processor affinity set to `XAUDIO2_DEFAULT_PROCESSOR`.
