There are several ways of storing and accessing blocks of memory in an OCaml program, including
bytesandstringvalues for mutable and immutable strings that reside in the OCaml heapbigarrayvalues for reference-counted blocks that reside in the OCaml heaps- Ctypes
ptrvalues that can be used to address arbitrary addresses using typed descriptions of the memory layout. - Ctypes
carrayvalues that provide bounds-checked access toptr-addressed memory.
The Memcpy module provides functions for safely and efficiently copying blocks of memory between these different representations.
