p The hash value returned is will be identical across machines of different architectures. This allows hash tables to be built on one machine and correctly used on another of a different architecture. The hash value returned is also guaranteed .Em not to be the bit pattern of all ones (~0UL). .Sh IMPLEMENTATION NOTES The library internally uses unsigned 32 bit arithmetic to compute the hash value. .Sh SEE ALSO .Xr elf 3 , .Xr gelf 3
