+.BI "Elf_Arhdr *elf_getarhdr(Elf *" elf ");"
+.fi
+
+.SH DESCRIPTION
+Return a
+.B Elf_Arhdr *
+describing the archive header of the archive member currently referred
+to by an ELF descriptor.
+
+The
+.B Elf_Arhdr
+structure is defined as:
+
+.P
+.nf
+typedef struct {
+ char *ar_name; /* Name of archive member. */
+ time_t ar_date; /* File date. */
+ uid_t ar_uid; /* User ID. */
+ gid_t ar_gid; /* Group ID. */
+ mode_t ar_mode; /* File mode. */
+ int64_t ar_size; /* File size. */
+ char *ar_rawname; /* Original name of archive member. */
+} Elf_Arhdr;
+.fi
+
+.SH PARAMETERS
+.TP
+.I elf
+An ELF descriptor referring to a member of an archive file.
+
+.SH RETURN VALUE
+If
+.I elf
+refers to an archive member,
+.B elf_getarhdr()
+returns a pointer to its archive header. This pointer is valid only until
+.B elf_next()
+or
+.B elf_rand()
+update the parent archive ELF descriptor,
+or
+.BR elf_end()
+is called on the parent archive ELF descriptor. If
+.I elf
+does not refer to an archive member or the header cannot be
+acquired then NULL is returned.
