dwarf_fde_cie_list_dealloc(Dwarf_Debug dbg, Dwarf_Cie *cie_list,
Dwarf_Signed cie_count, Dwarf_Fde *fde_list, Dwarf_Signed fde_count);
void
dwarf_funcs_dealloc(Dwarf_Debug dbg, Dwarf_Func *funcs,
Dwarf_Signed funccount);

Dwarf_Signed globalcount);
void
dwarf_pubtypes_dealloc(Dwarf_Debug dbg, Dwarf_Type *pubtypes,
Dwarf_Signed pubtypecount);
void
dwarf_ranges_dealloc(Dwarf_Debug dbg, Dwarf_Ranges *ranges,
Dwarf_Signed rangecount);
void

Dwarf_Signed linecount);
void

Dwarf_Signed typecount);

Dwarf_Signed weakcount);
DESCRIPTION
The function dwarf_dealloc() is used by applications to indicate that
memory areas returned by DWARF Access Library (libdwarf, -ldwarf) may be
safely disposed off. Due to the way memory is managed in the current
implementation, the use of dwarf_dealloc() is only necessary for a small
set of DWARF types.
indicated type must match that of the object being passed in argument
ptr. Valid values for the type argument are:
DW_DLA_ABBREV An object of type Dwarf_Abbrev, as returned by a call
to the function dwarf_get_abbrev(3).
DW_DLA_DIE An object of type Dwarf_Die, as returned by calls to
the functions dwarf_child(3), dwarf_offdie(3) or
dwarf_siblingof(3).
DW_DLA_FRAME_BLOCK An array of objects of type Dwarf_Frame_op, as
returned by a call to the function
dwarf_expand_frame_instructions(3).
Calls to dwarf_dealloc() with other values for argument type are no-ops
in this implementation.
The functions dwarf_fde_cie_list_dealloc(), dwarf_funcs_dealloc(),
dwarf_globals_dealloc(), dwarf_pubtypes_dealloc(),
dwarf_ranges_dealloc(), dwarf_srclines_dealloc(), dwarf_types_dealloc(),
dwarf_vars_dealloc() and dwarf_weaks_dealloc() are provided for
compatibility with other implementations of the DWARF(3) API. Due to the
way memory is managed in the current implementation, these functions are
effectively no-ops.
See dwarf(3) for more information about the memory management scheme in
this implementation of the DWARF(3) API.
RETURN VALUES
Functions dwarf_dealloc(), dwarf_fde_cie_list_dealloc(),
dwarf_funcs_dealloc(), dwarf_globals_dealloc(), dwarf_pubtypes_dealloc(),
dwarf_ranges_dealloc(), dwarf_srclines_dealloc(), dwarf_types_dealloc(),
dwarf_vars_dealloc() and dwarf_weaks_dealloc() have no return value.
