1//! # FFI bindings to **libpmemblk**
2//!
3//! The **libpmemblk** library supports arrays of pmem-resident blocks, all the same size, that are atomically updated.
4//! For example, a program keeping a cache of fixed-size objects in pmem might find this library useful.
5//!
6//! > This is **not** an official port of the NVM Library.
7//! >
8//! > The official **libpmemblk** documentation can be found at: [http://pmem.io/nvml/libpmemblk/](http://pmem.io/nvml/libpmemblk/)
