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));
