Development files for the low-level persistent memory library
The libpmem provides low level persistent memory support. In particular,
support for the persistent memory instructions for flushing changes
to pmem is provided. This package provides the v2 API.
This library is provided for software which tracks every store to
pmem and needs to flush those changes to durability. Most developers
will find higher level libraries like libpmemobj to be much more
convenient.
