Data Fields | |
| uint32_t | call_timeout |
| The timeout for the service call in milliseconds. More... | |
| uint32_t | return_diagnostics |
| Bit mask that defines the diagnostic information to be returned from the server. More... | |
| uint32_t | request_handle |
| Request handle used for the service call. More... | |
| bool | keep_request |
| Keep the service request allocated until the callback, so the application can use it there. | |
| uint32_t call_timeout |
The timeout for the service call in milliseconds.
| uint32_t request_handle |
Request handle used for the service call.
The request handle is sent to the server in the RequestHeader and is used to cancel service invocations. If the request handle is not set (initial value is 0), a unique number is set by the SDK.
The SDK is using numbers above 1.000.000 for creating unique numbers. An application must make sure to only use numbers below 1.000.000 to avoid conflicts when cancel is called.
| uint32_t return_diagnostics |
Bit mask that defines the diagnostic information to be returned from the server.
The default setting is 0.
| Bit Value | Diagnostics to return | Define |
