# Internal Headers

libdpm-core.so's own headers, used by its sources and never installed.

They declare the types and functions the library's translation units share with each other: the definitions behind the opaque handles `<dpm/core.h>` exposes, and the helpers those sources call across file boundaries.

Nothing here is part of the public interface. The install rule ships `include/dpm/` alone, so a consumer or a module compiles against `<dpm/core.h>` and never sees this directory.
