elf_getarhdr -- retrieve ar(1) header for an archive member LIBRARY
ELF Access Library (libelf, -lelf) SYNOPSIS
#include <libelf.h> Elf_Arhdr * elf_getarhdr(Elf *elf); DESCRIPTION
The elf_getarhdr() function returns a pointer to an archive member header for a descriptor elf. This descriptor must have been returned by a prior call to elf_begin(3), and must be a descriptor for a member inside an ar(1) archive. Structure Elf_Arhdr includes the following members: char * ar_name A pointer to a null terminated string containing the translated name of the archive member. char * ar_rawname A pointer to a null terminated string containing the untranslated name for the archive member, including all ar(1) formatting charac- ters and trailing white space. time_t ar_date The timestamp associated with the member. uid_t ar_uid The uid of the creator of the member. gid_t ar_gid The gid of the creator of the member. mode_t ar_mode The file mode of the member. size_t ar_size The size of the member in bytes. RETURN VALUES
This function returns a valid pointer to an Elf_Arhdr structure if successful, or NULL if an error is encountered. ERRORS
Function elf_getarhdr() may fail with the following errors: [ELF_E_ARGUMENT] Argument elf was NULL. [ELF_E_ARGUMENT] Argument elf was not a descriptor for a member of an ar(1) archive. SEE ALSO

elf_getarhdr - retrieve archive member header SYNOPSIS
cc [ flag ... ] file ... -lelf [ library... ] #include <libelf.h> Elf_Arhdr *elf_getarhdr(Elf *elf); DESCRIPTION
elf_getarhdr() 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; elf_getarhdr() then returns a null value. The header includes the following members. char *ar_name; time_t ar_date; uid_t ar_uid; gid_t ar_gid; mode_t 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_raw- name member holds a null-terminated string that represents the original name bytes in the file, including the terminating slash and trail- ing 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() on elf_begin(3ELF)). // 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. ATTRIBUTES
