elf_hash(3ELF)		     ELF Library Functions		elf_hash(3ELF)

NAME
       elf_hash	- compute hash value

SYNOPSIS
       cc [ flag ... ] file ...	-lelf [	library	... ]
       #include	<libelf.h>

       unsigned	long elf_hash(const char *name);

DESCRIPTION
       The  elf_hash() function	computes a hash	value, given a null terminated
       string, name. The returned hash value, h, can be	used as	a  bucket  in-
       dex, typically after computing h	mod x to ensure	appropriate bounds.

       Hash  tables  may  be  built on one machine and used on another because
       elf_hash() uses unsigned	arithmetic to avoid possible   differences  in
       various	machines'  signed  arithmetic. Although	name is	shown as char*
       above, elf_hash() treats	it as unsigned char* to	avoid  sign  extension
       differences.  Using  char*  eliminates  type conflicts with expressions
       such as elf_hash(name).

       ELF files' symbol hash tables are computed  using  this	function  (see
       elf_getdata(3ELF) and elf32_xlatetof(3ELF)). The	hash value returned is
       guaranteed not to be the	bit pattern of all ones	( ~0UL).
