NAME
     dwarf_get_elf -- retrieve the Elf descriptor associated with a Dwarf_Debug instance

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     int
     dwarf_get_elf(Dwarf_Debug dbg, Elf **elf, Dwarf_Error *err);

DESCRIPTION
     Function dwarf_get_elf() returns the Elf descriptor associated with a Dwarf_Debug instance.

     Argument dbg should be a handle to a valid Dwarf_Debug instance returned by a prior call to dwarf_init(3) or dwarf_elf_init(3).

     Argument elf points a location into which a handle to an Elf descriptor will be written.

     Argument err is used to record error information in case of failure.

RETURN VALUES
     On success, function dwarf_get_elf() returns DW_DLV_OK.  In case of an error, it returns DW_DLV_ERROR and sets argument err.

EXAMPLES
     To retrieve the Elf instance associated with a Dwarf_Debug instance use:

	   Dwarf_Debug dbg;
	   Dwarf_Error de;
	   Elf *elf;

	   ... allocate dbg using dwarf_init() etc ...

	   if (dwarf_get_elf(dbg, &elf, &de) != DW_DLV_OK)
		   errx(EXIT_FAILURE, "dwarf_get_elf: %s", dwarf_errmsg(de));
