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 sec-
     tion 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.

NAME

     dwarf_next_types_section -- step through .debug_types sections in a debug context

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_next_types_section(Dwarf_Debug dbg, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_next_types_section() steps through the ``.debug_types'' sections found in a debug context.

     Argument dbg should reference a DWARF debug context allocated using dwarf_init(3).  Argument err should point to a location that will hold an
     error descriptor in case of an error.

     When a DWARF debug context is allocated using dwarf_init(3), an internal pointer associated with the context will point to the first
     ``.debug_types'' section present in the debug object.  When the application calls function dwarf_next_types_section(), this internal pointer
     will move to the next ``.debug_types'' section present.  On stepping past the last ``.debug_types'' section left in the debug context, func-
     tion dwarf_next_types_section() returns DW_DLV_NO_ENTRY.  The next call to the function will restart from the first ``.debug_types'' section
     in the debug context.

     Application code should call function dwarf_next_cu_header_c(3) to iterate though the type units associated with the current ``.debug_types''
     section.

RETURN VALUES

     On success, function dwarf_next_types_section() returns DW_DLV_OK.

     In case of an error, it returns DW_DLV_ERROR and sets argument err.  When there are no more ``.debug_types'' sections left to traverse, it
     returns DW_DLV_NO_ENTRY.

COMPATIBILITY

     This function is an extension to the DWARF(3) API.

ERRORS

     The dwarf_next_types_section() function may fail with the following errors:

     [DW_DLE_ARGUMENT]	Argument dbg was NULL.

EXAMPLES

     To iterate though every type unit in all the ``.debug_types'' sections found in a debug context:

	   Dwarf_Debug dbg;
	   Dwarf_Sig8 sig8;
	   Dwarf_Unsigned typeoff;
	   Dwarf_Error de;

	   ... allocate dbg using dwarf_init() etc ...

	   do {
		   while ((ret = dwarf_next_cu_header_c(dbg, 0, NULL, NULL, NULL,
		       NULL, NULL, NULL, &sig8, &typeoff, NULL, &de)) == DW_DLV_OK) {
			   /* Access DIEs etc ... */
		   }
	   } while (dwarf_next_types_section(dbg, &de) == DW_DLV_OK);
