NAME

dwarf_get_section_max_offsets, dwarf_get_section_max_offsets_b — return the size of DWARF sections

LIBRARY

DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

#include <libdwarf.h>

int
dwarf_get_section_max_offsets(Dwarf_Debug dbg, Dwarf_Unsigned *debug_info, Dwarf_Unsigned *debug_abbrev, Dwarf_Unsigned *debug_line, Dwarf_Unsigned *debug_loc, Dwarf_Unsigned *debug_aranges, Dwarf_Unsigned *debug_macinfo, Dwarf_Unsigned *debug_pubnames, Dwarf_Unsigned *debug_str, Dwarf_Unsigned *debug_frame, Dwarf_Unsigned *debug_ranges, Dwarf_Unsigned *debug_pubtypes);

int
dwarf_get_section_max_offsets_b(Dwarf_Debug dbg, Dwarf_Unsigned *debug_info, Dwarf_Unsigned *debug_abbrev, Dwarf_Unsigned *debug_line, Dwarf_Unsigned *debug_loc, Dwarf_Unsigned *debug_aranges, Dwarf_Unsigned *debug_macinfo, Dwarf_Unsigned *debug_pubnames, Dwarf_Unsigned *debug_str, Dwarf_Unsigned *debug_frame, Dwarf_Unsigned *debug_ranges, Dwarf_Unsigned *debug_pubtypes, Dwarf_Unsigned *debug_types);

DESCRIPTION

Function dwarf_get_section_max_offsets_b() retrieves the sizes of the DWARF sections in a DWARF debug context. Argument dbg should reference a DWARF debug context allocated using dwarf_init(3). The function stores the size of each DWARF section to the location pointed to by the argument corresponding to the section name. If a DWARF section does not exist, the location pointed to by the argument corresponding to that section will be set to zero.

A value of NULL may be used for any of the arguments debug_info, debug_abbrev, debug_line, debug_loc, debug_aranges, debug_macinfo, debug_pubnames, debug_str, debug_frame, debug_ranges, debug_pubtypes and debug_types if the caller is not interested in the respective section size.

Function dwarf_get_section_max_offsets() is identical to function dwarf_get_section_max_offsets_b() except that it does not provide argument debug_types, and thus cannot return the size of the “.debug_types” section.

RETURN VALUES

On success, these functions return DW_DLV_OK. If argument dbg is NULL, they return DW_DLV_ERROR.
