# XGameSaveGetContainerInfo

> XGameSaveGetContainerInfo

# XGameSaveGetContainerInfo

检索 **XGameSaveProvider** 中容器的信息。

## Syntax

```cpp theme={null}
HRESULT XGameSaveGetContainerInfo(  
         XGameSaveProviderHandle provider,  
         const char* containerName,  
         void* context,  
         XGameSaveContainerInfoCallback* callback  
)  
```

### Parameters

*provider*   \_In\_\
类型：XGameSaveProviderHandle

具有所需容器的 **XGameSaveProvider** 句柄。

*containerName*   \_In\_z\_\
类型：char\*

要检索其信息的容器的名称，如果找到，将只返回一个结果。如果需要多个容器，请使用 [XGameSaveEnumerateContainerInfo](/reference/system/xgamesave/functions/xgamesaveenumeratecontainerinfo) 或 [XGameSaveEnumerateContainerInfoByName](/reference/system/xgamesave/functions/xgamesaveenumeratecontainerinfobyname)。

*context*   \_In\_opt\_\
类型：void\*

指向调用对象的指针，用于提供上下文。

*callback*   \_In\_\
类型：XGameSaveContainerInfoCallback\*

用于确定 [XGameSaveContainerInfo](/reference/system/xgamesave/structs/xgamesavecontainerinfo) 调用的结果并从中收集数据的回调函数。

### Return value

类型：HRESULT

函数结果

#### 常见错误

* E\_GS\_INVALID\_CONTAINER\_NAME
* E\_GS\_USER\_CANCELED
* E\_GS\_CONTAINER\_NOT\_IN\_SYNC
* E\_GS\_CONTAINER\_SYNC\_FAILED
* E\_GS\_HANDLE\_EXPIRED

## Remarks

<Note>此函数在时间敏感型线程上调用是不安全的。有关详细信息，请参阅[时间敏感型线程](https://learn.microsoft.com/gaming/gdk/docs/gdk-dev/console-dev/overviews/threads/time-sensitive-threads)。</Note>

容器是元数据的集合以及其中一组 Blob 的引用点。如果提前知道容器名称，则可以使用此 API 仅返回该容器的信息。这对于返回有关玩家的特定信息很有用，而不是每次需要信息时都要求提供所有信息。你可以在 [XGameSaveContainerInfo](/reference/system/xgamesave/structs/xgamesavecontainerinfo) 结构中找到 **XGameSaveContainer** 的组成。

```cpp theme={null}
void Sample::_GetContainerInfo(const char* name) 
{ 
    XGameSaveContainerInfoCallback* callback = [](_In_ const XGameSaveContainerInfo* info, _In_ void* ctx) -> bool 
    { 
        auto self = reinterpret_cast<Sample*>(ctx); 
        self->_UpdateContainerList(info); 
        return true; 
    }; 
  
    HRESULT hr = XGameSaveGetContainerInfo(_provider, name, this, callback); 
    if (FAILED(hr)) 
    { 
        _HandleContainerErrors(name, hr); 
    } 
} 
 
void Sample::_UpdateContainerList(const XGameSaveContainerInfo* container) 
{ 
    //update UX 
    printf("%s - %s: %I64dbytes %d blobs\n", container->name, container->displayName, container->totalSize, container->blobCount); 
    if (strcmp(container->name, "AutoSave") == 0) 
    { 
        _ReadContainerBlobsAsync(container); 
    } 
} 
 
void Sample::_HandleContainerErrors(const char* name, HRESULT hr) 
{ 
    switch (hr) 
    { 
    case E_GS_INVALID_CONTAINER_NAME: 
        printf("\'%s\' name is invalid for a container", name); 
        break; 
    case E_GS_USER_CANCELED: 
        printf("Container %s failed to sync user canceled hr=0x%08x\n", name, hr); 
        break; 
    case E_GS_CONTAINER_NOT_IN_SYNC: 
    case E_GS_CONTAINER_SYNC_FAILED: 
        printf("Container %s failed to sync hr=0x%08x\n", name, hr); 
        break; 
    case E_GS_HANDLE_EXPIRED: 
        printf("Container %s failed, re-initialize provider", name); 
        break; 
    case S_OK: 
        break; 
    default: 
        printf("Unknown Container error %s hr=0x%08X\n", name, hr); 
    } 
}
```
