Description

   	char		ar_name;
   	time_t		ar_date;
   	long		ar_uid;
   	long		ar_gid;
   	unsigned long	ar_mode;
   	off_t		ar_size;
   	char		ar_rawname;

An archive member name, available through ar_name, is a null-terminated string, with the ar format control characters removed. The ar_rawname 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 archive format.

In addition to ``regular'' archive members, the archive format defines some special members. All special member names begin with a slash (/), distinguishing them from regular members (whose names may not contain a slash). These special members have the names (ar_name) 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 elf_getarsym. The information in the symbol table is useful for random archive processing [see elf_rand(ELF)].

• 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 ar_name to the appropriate value.

Under some error conditions, a member's name might not be available. Although this causes the library to set ar_name to a null pointer, the ar_rawname member will be set as usual.
