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_ptrGetMemoryBlockPtrGetMemoryBlockPtrget_memory_block_ptr in
HDevelop.
Signature
Description
get_memory_block_ptrget_memory_block_ptrGetMemoryBlockPtrGetMemoryBlockPtrget_memory_block_ptr returns the data pointer to the beginning of a
memory block in PointerPointerPointerpointerpointer and its size in bytes in SizeSizeSizesizesize.
MemoryBlockHandleMemoryBlockHandleMemoryBlockHandlememoryBlockHandlememory_block_handle is the handle of the memory block.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters
