NAME

elf_getarsym() - retrieve archive symbol table

SYNOPSIS

Invocation: cc [ﬂag]... ﬁle...

-lelf [library]...

#include <libelf.h>

Elf_Arsym *elf_getarsym(

Elf *

elf,

size_t * ptr

);

DESCRIPTION

elf_getarsym()

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 fol-

lowing members.

char *as_name;

size_t as_off;

unsigned long as_hash;

These members are deﬁned as follows:

as_name

A pointer to a null-terminated symbol name.

as_off 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 to access the desired archive member.

as_hash

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 zero 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.
