DWARF_GET_CU_DIE_OFFSET(3) FreeBSD Library Functions Manual
NAME
dwarf_get_arange_cu_header_offset, dwarf_get_cu_die_offset - retrieve
compilation unit offsets
LIBRARY
DWARF Access Library (libdwarf, -ldwarf)
SYNOPSIS
#include <libdwarf.h>
int
dwarf_get_arange_cu_header_offset(Dwarf_Arange ar, Dwarf_Off *ret,
Dwarf_Error *err);
int
dwarf_get_cu_die_offset(Dwarf_Arange ar, Dwarf_Off *ret,
Dwarf_Error *err);
DESCRIPTION
These functions retrieve the offsets, relative to the ".debug_info" DWARF
section, of the debugging information entries describing the compilation
unit associated with a Dwarf_Arange descriptor.
Function dwarf_get_arange_cu_header_offset() retrieves the offset of the
compilation unit header associated with argument ar, and stores it in the
location pointed to by argument ret.
Function dwarf_get_cu_die_offset() retrieves the offset of the debugging
information entry for the compilation unit associated with argument ar,
and stores it in the location pointed to by argument ret.
If argument err is not NULL, these functions will use it to store error
information, in case of an error.
RETURN VALUES
On success, these functions returns DW_DLV_OK. In case of an error, they
return DW_DLV_ERROR and set the argument err.
ERRORS
These functions may fail with:
[DW_DLE_ARGUMENT] Argument ar was not a valid Dwarf_Arange descriptor.
[DW_DLE_ARGUMENT] Argument ret was NULL.
