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.
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.
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).
