Member Function Documentation

◆ get_named_type()

bool tinfo_t::get_named_type	(	const til_t *	til,
		const char *	name,
		type_t	decl_type = `BTF_TYPEDEF`,
		bool	resolve = `true`,
		bool	try_ordinal = `true`
	)

inline

Create a tinfo_t object for an existing named type.

Parameters

til	type library to use
name	name of the type to link to
decl_type	if the reference was explicitly specified with the type tag (BTF_STRUCT/BTF_UNION/BTF_ENUM) you may specify it. the kernel will accept only the specified tag after resolving the type. If the resolved type does not correspond to the explicitly specified tag, the type will be considered as undefined
resolve	true: immediately resolve the type and return success code. false: return true but do not immediately resolve the type
try_ordinal	true: try to replace name reference by an ordinal reference

◆ get_numbered_type()

bool tinfo_t::get_numbered_type	(	const til_t *	til,
		uint32	ordinal,
		type_t	decl_type = `BTF_TYPEDEF`,
		bool	resolve = `true`
	)

inline

Create a tinfo_t object for an existing ordinal type.

Parameters

til	type library to use
ordinal	number of the type to link to
decl_type	if the reference was explicitly specified with the type tag (BTF_STRUCT/BTF_UNION/BTF_ENUM) you may specify it. the kernel will accept only the specified tag after resolving the type. If the resolved type does not correspond to the explicitly specified tag, the type will be considered as undefined
resolve	true: immediately resolve the type and return success code false: return true but do not immediately resolve the type

◆ deserialize()

bool tinfo_t::deserialize	(	const til_t *	til,
		const qtype *	ptype,
		const qtype *	pfields = `nullptr`,
		const qtype *	pfldcmts = `nullptr`
	)

inline

Deserialize a type string into a tinfo_t object.

◆ is_correct()

bool tinfo_t::is_correct ( void ) const

inline

Is the type object correct?.

It is possible to create incorrect types. For example, we can define a function that returns a enum and then delete the enum type. If this function returns false, the type should not be used in disassembly. Please note that this function does not verify all involved types: for example, pointers to undefined types are permitted.

◆ get_realtype()

type_t tinfo_t::get_realtype ( bool full = false ) const

inline

Get the resolved base type.

Deserialization options:

if full=true, the referenced type will be deserialized fully, this may not always be desirable (slows down things)
if full=false, we just return the base type, the referenced type will be resolved again later if necessary (this may lead to multiple resolvings of the same type) imho full=false is a better approach because it does not perform unnecessary actions just in case. however, in some cases the caller knows that it is very likely that full type info will be required. in those cases full=true makes sense

◆ get_decltype()

THREAD_SAFE type_t tinfo_t::get_decltype ( void ) const

inline

Get declared type (without resolving type references; they are returned as is).

Obviously this is a very fast function and should be used instead of get_realtype() if possible.

◆ get_size()

size_t tinfo_t::get_size	(	uint32 *	p_effalign = `nullptr`,
		int	gts_code = `0`
	)		const

inline

Get the type size in bytes.

Parameters

p_effalign	buffer for the alignment value
gts_code	combination of GTS_... constants

Returns: BADSIZE in case of problems

◆ get_unpadded_size()

size_t tinfo_t::get_unpadded_size ( void ) const

inline

Get the type size in bytes without the final padding, in bytes.

For some UDTs get_unpadded_size() != get_size()

◆ is_typeref()

THREAD_SAFE bool tinfo_t::is_typeref ( void ) const

inline

Is this type a type reference?.

Type references cannot be modified. Once created, they do not change. Because of this, the set_... functions applied to typerefs create a new type id. Other types are modified directly.

◆ get_type_name()

bool tinfo_t::get_type_name ( qstring * out ) const

inline

Does a type refer to a name?.

If yes, fill the provided buffer with the type name and return true. Names are returned for numbered types too: either a user-defined nice name or, if a user-provided name does not exist, an ordinal name (like #xx, see create_numbered_type_name()).

◆ get_final_type_name()

bool tinfo_t::get_final_type_name ( qstring * out ) const

inline

Use in the case of typedef chain (TYPE1 -> TYPE2 -> TYPE3...TYPEn).

Returns: the name of the last type in the chain (TYPEn). if there is no chain, returns TYPE1

◆ get_next_type_name()

bool tinfo_t::get_next_type_name ( qstring * out ) const

inline

Use In the case of typedef chain (TYPE1 -> TYPE2 -> TYPE3...TYPEn).

Returns: the name of the next type in the chain (TYPE2). if there is no chain, returns failure

◆ is_from_subtil()

bool tinfo_t::is_from_subtil ( void ) const

inline

Was the named type found in some base type library (not the top level type library)?.

If yes, it usually means that the type comes from some loaded type library, not the local type library for the database

◆ is_forward_decl()

bool tinfo_t::is_forward_decl ( void ) const

inline

Is this a forward declaration?.

Forward declarations are placeholders: the type definition does not exist

◆ get_ptrarr_object()

tinfo_t tinfo_t::get_ptrarr_object ( void ) const

inline

BT_PTR & BT_ARRAY: get the pointed object or array element.

If the current type is not a pointer or array, return empty type info.

◆ get_pointed_object()

tinfo_t tinfo_t::get_pointed_object ( void ) const

inline

BT_PTR: get type of pointed object.

If the current type is not a pointer, return empty type info. See also get_ptrarr_object() and remove_pointer()

◆ get_methods()

bool tinfo_t::get_methods ( udtmembervec_t * methods ) const

inline

BT_COMPLEX: get a list of member functions declared in this udt.

Returns: false if no member functions exist

◆ set_methods()

bool tinfo_t::set_methods ( udtmembervec_t & methods )

inline

BT_COMPLEX: set the list of member functions.

This function consumes 'methods' (makes it empty).

Returns: false if this type is not a udt, or if the given list is empty

◆ find_udt_member()

int tinfo_t::find_udt_member	(	struct udt_member_t *	udm,
		int	strmem_flags
	)		const

inline

BTF_STRUCT,BTF_UNION: Find a udt member.

at the specified offset (STRMEM_OFFSET)
with the specified index (STRMEM_INDEX)
with the specified type (STRMEM_TYPE)
with the specified name (STRMEM_NAME)
Returns
the index of the found member or -1

◆ requires_qualifier()

bool tinfo_t::requires_qualifier	(	qstring *	out,
		const char *	name,
		uint64	offset
	)		const

inline

Requires full qualifier? (name is not unique)

Parameters

out	qualifier. may be nullptr
name	field name
offset	field offset in bits

Returns: if the name is not unique, returns true

◆ append_covered()

bool tinfo_t::append_covered	(	rangeset_t *	out,
		uint64	offset = `0`
	)		const

inline

Calculate set of covered bytes for the type.

Parameters

out	pointer to the output buffer. covered bytes will be appended to it.
offset	delta in bytes to add to all calculations. used internally during recurion.

◆ calc_gaps()

bool tinfo_t::calc_gaps ( rangeset_t * out ) const

inline

Calculate set of padding bytes for the type.

Parameters

out	pointer to the output buffer; old buffer contents will be lost.

◆ print()

bool tinfo_t::print	(	qstring *	out,
		const char *	name = `nullptr`,
		int	prtype_flags = `PRTYPE_1LINE`,
		int	indent = `0`,
		int	cmtindent = `0`,
		const char *	prefix = `nullptr`,
		const char *	cmt = `nullptr`
	)		const

inline

Get a C-like string representation of the type.

Parameters

out	output string
name	name of type
prtype_flags	Type printing flags
indent	structure level indent
cmtindent	comment indent
prefix	string prepended to each line
cmt	comment text

Returns: success

◆ set_attrs()

bool tinfo_t::set_attrs ( type_attrs_t * tav )

inline

Set type attributes.

If necessary, a new typid will be created. this function modifies tav! (returns old attributes, if any)

Returns: false: bad attributes

◆ create_forward_decl()

tinfo_code_t tinfo_t::create_forward_decl	(	til_t *	til,
		type_t	decl_type,
		const char *	name,
		int	ntf_flags = `0`
	)

inline

Create a forward declaration.

decl_type: BTF_STRUCT, BTF_UNION, or BTF_ENUM

◆ get_stock()

static tinfo_t tinfo_t::get_stock ( stock_type_id_t id )

inlinestatic

Get stock type information.

This function can be used to get tinfo_t for some common types. The same tinfo_t will be returned for the same id, thus saving memory and increasing the speed Please note that retrieving the STI_SIZE_T or STI_SSIZE_T stock type, will also have the side-effect of adding that type to the 'idati' TIL, under the well-known name 'size_t' or 'ssize_t' (respectively). The same is valid for STI_COMPLEX64 and STI_COMPLEX64 stock types with names 'complex64_t' and 'complex128_t' (respectively).

◆ convert_array_to_ptr()

bool tinfo_t::convert_array_to_ptr ( void )

inline

Convert an array into a pointer.

type[] => type *

◆ remove_ptr_or_array()

bool tinfo_t::remove_ptr_or_array ( void )

inline

Replace the current type with the ptr obj or array element.

This function performs one of the following conversions:

type[] => type
type* => type If the conversion is performed successfully, return true
