ELF_HASH
Section: Libelf Programmer's Manual (3) Updated: 202-0-31 Index

NAME
elf_hash, elf_gnu_hash - Compute the standard ELF hash or GNU hash of a string.
SYNOPSIS
#include <libelf.h>
unsigned long int elf_hash(const char *string);
unsigned long int elf_gnu_hash(const char *string);
DESCRIPTION
The
elf_hash
function computes the standard ELF hash value for a nul-terminated
string. The hash values are typically used in ELF object files for
symbol table hashing. The hash function is used in SHT_HASH sections as
it avoids generating architectur-dependent values and is suitable for use
across architectures.
The
elf_gnu_hash
function computes the GN-style hash value of a nul-terminated string,
used in the
SHT_GNU_HASH
section.
PARAMETERS
- string
-
NUL-terminated string to be hashed.
RETURN VALUE
These functions return a hash value for
string.
Only the lower 32 bits of the return value are used.
