ELF_NEXT(3)

NAME
elf_next - provide sequential access to the next archive member

SYNOPSIS
libelf
#include <libelf.h>
Elf_Cmd
elf_next(Elf *elf);

DESCRIPTION
The elf_next() function causes the ELF archive descriptor corresponding to argument elf to be adjusted to provide access to the next member in the archive on a subsequent call to elf_begin().

The return value of elf_next() is suitable for use in a loop invoking elf_begin().

RETURN VALUES
If successful, function elf_next() returns the value ELF_C_READ. Otherwise, if argument elf was not associated with an archive, or if it was NULL, or if any other error occurred, the value ELF_C_NULL is returned.

EXAMPLES
To process all the members of an archive use:

    Elf_Cmd cmd;
    Elf *archive, *e;
    ...
    cmd = ELF_C_READ;
    archive = elf_begin(fd, cmd, NULL);
    while ((e = elf_begin(fd, cmd, archive)) != (Elf *) 0)
    {
    	... process `e' here ...
    	cmd = elf_next(e);
    	elf_end(e);
    }
    elf_end(archive);

ERRORS
Function elf_next() may fail with the following error:

[ELF_E_ARGUMENT]
    Argument elf was not associated with a containing ar(1) archive.

[ELF_E_ARGUMENT]
    An error was encountered while parsing the archive containing argument elf.
