Function Documentation

get_named_type()

idaman int ida_export get_named_type	(	const til_t *	ti,
		const char *	name,
		int	ntf_flags,
		const type_t **	type = nullptr,
		const p_list **	fields = nullptr,
		const char **	cmt = nullptr,
		const p_list **	fieldcmts = nullptr,
		sclass_t *	sclass = nullptr,
		uint32 *	value = nullptr
	)

Get named typeinfo.

The returned pointers are pointers to static storage.
They are valid until free_til(), set_named_type(), del_named_type(),
rename_named_type(), set_numbered_type(), del_numbered_type(),
and idb structure/enum manipulation (in other words, until til_t is changed).

Parameters

ti	pointer to type information library
name	name of type
ntf_flags	combination of Flags for named types
type	ptr to ptr to output buffer for the type info
fields	ptr to ptr to the field/args names. may be nullptr
cmt	ptr to ptr to the main comment. may be nullptr the comment may has TPOS_REGCMT as its first byte
fieldcmts	ptr to ptr to the field/args comments. may be nullptr
sclass	ptr to storage class
value	ptr to symbol value. for types, ptr to the ordinal number

Return values

0	can't find the named type (or name==nullptr)
1	ok, the buffers are filled with information (if not nullptr)
2	ok, found it in a base til

get_named_type64()

int idaapi get_named_type64 ( const til_t *  ti, const char *  name, int  ntf_flags, const type_t **  type = nullptr, const p_list **  fields = nullptr, const char **  cmt = nullptr, const p_list **  fieldcmts = nullptr, sclass_t *  sclass = nullptr, uint64 *  value = nullptr  )

inline

See get_named_type() above.

Note

If the value in the 'ti' library is 32-bit, it will be sign-extended before being stored in the 'value' pointer.

tinfo_errstr()

idaman const char *ida_export tinfo_errstr

(

tinfo_code_t

code

)

Helper function to convert an error code into a printable string.

Additional arguments are handled using the functions from err.h

del_named_type()

idaman bool ida_export del_named_type	(	til_t *	ti,
		const char *	name,
		int	ntf_flags
	)

Delete information about a symbol.

Parameters

ti	type library
name	name of symbol
ntf_flags	combination of Flags for named types

Returns

success

first_named_type()

idaman const char *ida_export first_named_type	(	const til_t *	ti,
		int	ntf_flags
	)

Enumerate types.

Parameters

ti	type library. nullptr means the local type library for the current database.
ntf_flags	combination of Flags for named types

Returns

Type or symbol names, depending of ntf_flags. Returns mangled names. Never returns anonymous types. To include them, enumerate types by ordinals.

next_named_type()

idaman const char *ida_export next_named_type	(	const til_t *	ti,
		const char *	name,
		int	ntf_flags
	)

Enumerate types.

Parameters

ti	type library. nullptr means the local type library for the current database.
ntf_flags	combination of Flags for named types

Returns

Type or symbol names, depending of ntf_flags. Returns mangled names. Never returns anonymous types. To include them, enumerate types by ordinals.

Parameters

name	the current name. the name that follows this one will be returned.

copy_named_type()

idaman uint32 ida_export copy_named_type	(	til_t *	dsttil,
		const til_t *	srctil,
		const char *	name
	)

Copy a named type from one til to another.

This function will copy the specified type and all dependent types from the source type library to the destination library.

Parameters

dsttil	Destination til. It must have orginal types enabled
srctil	Source til.
name	name of the type to copy

Returns

ordinal number of the copied type. 0 means error

decorate_name()
