elf_hash(3)

elf_hash3

Compute a hash value for a string

Usage

#include <libelf.h>

unsigned long

elf_hash(const char *name);

Library

library “libelf”

Overview

Function elf_hash() computes a portable hash value for the null terminated string pointed to by argument name.

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 not to be the bit pattern of all ones (~0UL).

Implementation notes

The library internally uses unsigned 32 bit arithmetic to compute the hash value.
