XXH_INLINE_ALL (and XXH_PRIVATE_API) This build macro includes xxhash functions in static mode in order to inline them, and remove their symbol from the public list. Inlining offers great performance improvement on small keys, and dramatic ones when length is expressed as a compile-time constant. See https://fastcompression.blogspot.com/2018/03/xxhash-for-small-keys-impressive-power.html . Methodology : #define XXH_INLINE_ALL #include "xxhash.h" xxhash.c is automatically included. It's not useful to compile and link it as a separate object.
XXH_NAMESPACE, aka Namespace Emulation :
If you want to include and expose xxHash functions from within your own library, but also want to avoid symbol collisions with other libraries which may also include xxHash,
you can use XXH_NAMESPACE, to automatically prefix any public symbol from xxhash library with the value of XXH_NAMESPACE (therefore, avoid NULL and numeric values).
Note that no change is required within the calling program as long as it includes xxhash.h : regular symbol name will be automatically translated by this header.
