- Parameters
-
data | Specifies a pointer to data that will be copied into the data store for initialization. |
size | Specifies the size in bytes of the data store region being replaced. |

Update buffer sub-region data.
- Parameters
-
data | Specifies a pointer to the new data that will be copied into the data store. |
offset | Specifies the offset into the buffer object's data store where data replacement will begin, measured in bytes. |
size | Specifies the size in bytes of the data store region being replaced. |

By default, static buffer data will automatically stored when it comes to foreground.
This function is used to indicate whether external data needs to be used to update the buffer instead of using the default stored data.
- Parameters
-
needDefaultStoredData | Specifies whether to use the default stored data. |
Implemented in BufferMTL, and BufferGL.
