def read_memory_block(file_name: str) -> HHandle
Description
The operator read_memory_blockread_memory_blockReadMemoryBlockReadMemoryBlockReadMemoryBlockread_memory_block reads the file FileNameFileNameFileNameFileNamefileNamefile_name and
creates a new memory block in MemoryBlockHandleMemoryBlockHandleMemoryBlockHandleMemoryBlockHandlememoryBlockHandlememory_block_handle that is an identical

The default HALCON file extension for memory block files is '.bin'.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
