# 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`.
