ELF_GETARSYM 3ELF "Jul 11, 2001"
NAME
elf_getarsym - retrieve archive symbol table
SYNOPSIS

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

Elf_Arsym *elf_getarsym(Elf *elf, size_t *ptr);
DESCRIPTION

The elf_getarsym() function returns a pointer to the archive symbol table, if one is available for the ELF descriptor elf. Otherwise, the archive doesn't have a symbol table, an error occurred, or elf was null; elf_getarsym() then returns a null value. The symbol table is an array of structures that include the following members.

char *as_name;
size_t as_off;
unsigned long as_hash;

These members have the following semantics: as_name

A pointer to a null-terminated symbol name resides here.

as_off

This value is a byte offset from the beginning of the archive to the member's header. The archive member residing at the given offset defines the associated symbol. Values in as_off may be passed as arguments to elf_rand(). See elf_begin(3ELF) to access the desired archive member.

as_hash

This is a hash value for the name, as computed by elf_hash().

If ptr is non-null, the library stores the number of table entries in the location to which ptr points. This value is set to 0 when the return value is NULL. The table's last entry, which is included in the count, has a null as_name, a zero value for as_off, and ~0UL for as_hash.

The hash value returned is guaranteed not to be the bit pattern of all ones ( ~0UL).
