# HCTraceInit

初始化库的跟踪功能。

## Syntax

```cpp theme={null}
void HCTraceInit(  
)  
```

### Parameters

### Return value

Type: void

TBD

## Remarks

此函数在 HCInitialize 期间会被隐式调用。初始化采用引用计数机制，只要每次调用 HCTraceInit 都恰好与一次 HCTraceCleanup 调用配对，就支持多次调用 HCTraceInit 与 HCTraceCleanup。每次调用 HCTraceCleanup 时，客户端回调都将被全部清除。

## Requirements

**Header:** trace.h

**Library:** libHttpClient.GDK.lib
