ELF_NEXT(3)		 BSD Library Functions Manual		   ELF_NEXT(3)

NAME
     elf_next — provide sequential access to the next archive member

LIBRARY
     library “libelf”

SYNOPSIS
     #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.  Other‐
     wise, 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.
