DWARF_GET_ELF(3)        NetBSD Library Functions Manual       DWARF_GET_ELF(3)


NAME

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


LIBRARY

     library ``libdwarf''


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));
