elf_next – provide sequential access to the next archive member

LIBRARY SYNOPSIS DESCRIPTION RETURN VALUES EXAMPLES ERRORS SEE ALSO

ELF Access Library (libelf, -lelf)

#include <libelf.h>

Elf_Cmd
elf_next(Elf *elf);

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().

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.

To process all the members of an archive use:

Elf_Cmd cmd;
Elf *archive, *e;
amp;...
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);

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.
