Name

get_memory_block_ptrT_get_memory_block_ptrGetMemoryBlockPtrGetMemoryBlockPtrget_memory_block_ptr — Return the data pointer and size of a memory block.

Warning

It is not recommended to use the operator get_memory_block_ptrget_memory_block_ptrGetMemoryBlockPtrGetMemoryBlockPtrGetMemoryBlockPtrget_memory_block_ptr in HDevelop.
