# aclrtMemManagedLocation

```
typedef struct {
    aclrtMemManagedLocationType type;  // 内存所在位置
    int32_t id;                            // Device ID或NUMA（Non-Uniform Memory Access） ID
} aclrtMemManagedLocation;
```

当type为ACL_MEM_LOCATIONTYPE_INVALID、ACL_MEM_LOCATIONTYPE_HOST、ACL_MEM_LOCATIONTYPE_HOST_NUMA_CURRENT时，id无效。
