**StartTrace** and **FinishTrace** must be used in pairs, and **FinishTrace** matches the latest **StartTrace**. The two APIs can be used in nested mode. The stack data structure is used for matching during trace data parsing. The **limit** parameter is used for flow control, and you are advised to use the default value.

## How to Develop
1. Add the build dependencies to the build configuration file **base\hiviewdfx\hitrace\cmd\BUILD.gn**.
```
- external_deps = [ "hitrace_native:hitrace_meter"]
+ external_deps = [ "hitrace:hitrace_meter"]
```
2. Add the header file dependencies.

-| --trace_clock clock | Sets the type of the clock for adding a timestamp to a trace. The value can be **boot** (default), **global**, **mono**, **uptime**, or **perf**.|
-| --trace_begin | Starts capturing trace data. |
-| --trace_dump | Dumps trace data to the specified position. The default position is the console. |

-| -l, --list_categories | Lists the trace categories supported by the device. |
-| --overwrite | Sets the action to take when the buffer is full. If this option is used, the latest trace data is discarded. If this option is not used, the earliest trace data is discarded (default). |
