DWARF_ATTROFFSET(3) BSD Library Functions Manual DWARF_ATTROFFSET(3)NAME
dwarf_attroffset -- retrieve the section-relative offset of an attribute descriptor
LIBRARY
DWARF Access Library (libdwarf, -ldwarf)
SYNOPSIS
#include <libdwarf.h>
int
dwarf_attroffset(Dwarf_Attribute at, Dwarf_Off *ret_off, Dwarf_Error *err);
DESCRIPTION
Function dwarf_attroffset() retrieves the section-relative offset of the attribute descriptor referenced by argument at.
Argument ret_off should point to a location that is to hold the returned section-relative offset. If argument err is non-NULL, it is used to
return an error descriptor in case of an error.
RETURN VALUES
On success, function dwarf_attroffset() returns DW_DLV_OK.
In case of an error, it returns DW_DLV_ERROR and sets argument err.
COMPATIBILITY
This function is an extension to the DWARF(3) API.
ERRORS
The dwarf_attroffset() function may fail with the following errors:
[DW_DLE_ARGUMENT] Either of the arguments at or ret_off was NULL.

DWARF_GET_CU_DIE_OFFSET(3) BSD Library Functions Manual DWARF_GET_CU_DIE_OFFSET(3)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 com-
pilation 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.

In this case will the 1 gb of heap memory be returned... (9 Replies)
