Functions
| Name | Description |
|---|---|
| *OH_PurgeableMemory_Create (size_t size, OH_PurgeableMemory_ModifyFunc func, void *funcPara) | Creates a PurgeableMemory object. |
| OH_PurgeableMemory_Destroy (OH_PurgeableMemory *purgObj) | Destroys a PurgeableMemory object. |
| OH_PurgeableMemory_BeginRead (OH_PurgeableMemory *purgObj) | Starts a read operation on a PurgeableMemory object. If purgeable memory is reclaimed, the rebuilding function is called to rebuild it. |
| OH_PurgeableMemory_EndRead (OH_PurgeableMemory *purgObj) | Ends a read operation on a PurgeableMemory object. Now the system can reclaim purgeable memory. |
| OH_PurgeableMemory_BeginWrite (OH_PurgeableMemory *purgObj) | Begins a write operation on the PurgeableMemory object. If purgeable memory is reclaimed, the rebuilding function is called to rebuild it. |
| OH_PurgeableMemory_EndWrite (OH_PurgeableMemory *purgObj) | Ends a write operation on the PurgeableMemory object. Now the system can reclaim purgeable memory. |
| OH_PurgeableMemory_GetContent (OH_PurgeableMemory *purgObj) | Obtains the memory data of a PurgeableMemory object. |
| OH_PurgeableMemory_ContentSize (OH_PurgeableMemory *purgObj) | Obtains the memory data size of a PurgeableMemory object. |
| OH_PurgeableMemory_AppendModify (OH_PurgeableMemory *purgObj, OH_PurgeableMemory_ModifyFunc func, void *funcPara) | Adds a function for modifying a PurgeableMemory object. |
