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
       index, 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).
