elf_getarhdr(3E)elf_getarhdr(3E)NAMEelf_getarhdr - retrieve archive member header
[flag... ] file... [library] ...
returns a pointer to an archive member header, if one is available for
the ELF descriptor elf. Otherwise, no archive member header exists, an
error occurred, or elf was null; then returns a null value. The header
includes the following members.
unsigned long ar_mode;
An archive member name, available through is a null-terminated string,
with the format control characters removed. The member holds a null-
terminated string that represents the original name bytes in the file,
including the terminating slash and trailing blanks as specified in the
In addition to ``regular'' archive members, the archive format defines
some special members. All special member names begin with a slash dis‐
tinguishing them from regular members (whose names may not contain a
slash). These special members have the names defined below.
This is the archive symbol table. If present, it will
be the first archive member. A program may access the archive
symbol table through The information in the symbol table is use‐
ful for random archive processing (see elf_rand(3E)).
This member, if present, holds a string table for long
archive member names. An archive member's header contains a
16-byte area for the name, which may be exceeded in some file
systems. The library automatically retrieves long member names
from the string table, setting to the appropriate value.
Under some error conditions, a member's name might not be available.
Although this causes the library to set to a null pointer, the member
will be set as usual.
