XXH_PRIVATE_API This is useful if you want to include xxhash functions in static
mode in order to inline them, and remove their symbol from the public list. Methodology : define XXH_PRIVATE_API include "xxhash.h" xxhash.c
is automatically included. It's not useful to compile and link it as a separate module anymore.

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 another library which also includes xxHash,
you can use XXH_NAMESPACE, to automatically prefix any public symbol from xxhash library with the value of XXH_NAMESPACE (so avoid to keep it NULL and avoid 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.

XXH32() : Calculate the 32-bits hash of sequence "length" bytes stored at memory address "input". The memory between input & input+length must be valid (allocated and read-accessible). "seed" can be used to alter the result predictably. Speed on Core 2 Duo @ 3 GHz (single thread, SMHasher benchmark) : 5.4 GB/s XXH64() : Calculate the 64-bits hash of sequence of length "len" stored at memory address "input". "seed" can be used to alter the result predictably. This function runs 2x faster on 64-bits systems, but slower on 32-bits systems (see benchmark).

Default XXH result types are basic unsigned 32 and 64 bits. The canonical representation follows human-readable write convention, aka big-endian (large digits first). These functions allow transformation of hash result into and from its canonical format. This way, hash values can be written into a file or buffer, and remain comparable across different systems and programs.
