Typedef Documentation

typedef int idaapi h2ti_type_cb(const char *name, const tinfo_t &tif, const char *cmt, const uint64 *value, void *cb_data)

This callback will be called for each type/variable declaration.

Parameters

name	var/func/type name
tif	type info
cmt	main comment
value	symbol value
cb_data	data passed to callback

Return values

T_CBBRKDEF

the type declaration won't be saved in the til

typedef int printer_t(const char *format,...)

Specify a printing callback when parsing types.

See h2ti() and parse_decls().

Function Documentation

idaman int ida_export h2ti	(	til_t *	ti,
		lexer_t *	lx,
		const char *	input,
		int	flags = HTI_HIGH,
		h2ti_type_cb *	type_cb = NULL,
		h2ti_type_cb *	var_cb = NULL,
		printer_t *	print_cb = NULL,
		void *	_cb_data = NULL,
		abs_t	_isabs = abs_unk
	)

Convert declarations to type_t*.

This is a low level function - use parse_decls() or parse_decl()

Parameters

ti	type info library
lx	input lexer. may be NULL. always destroyed by h2ti()
input	file name or C declaration
flags	combination of Type formatting flags
type_cb	callback - for each type
var_cb	callback - for each var
print_cb	may pass msg() here
_cb_data	data passed to callbacks
_isabs	the expected abstracness of the type declaration(s)

Returns

number of errors (they are displayed using print_cb). zero means ok

idaman bool ida_export parse_decl	(	tinfo_t *	tif,
		qstring *	out,
		til_t *	til,
		const char *	decl,
		int	flags
	)

Parse ONE declaration.

If the input string contains more than one declaration, the first complete type declaration (PT_TYP) or the last variable declaration (PT_VAR) will be used.

Note

name & tif may be empty after the call!

Parameters

[out]	tif	type info
[out]	out	declared name
	til	type library to use. may be NULL
	decl	C declaration to parse
	flags	combination of Type parsing flags bits

Return values

true	ok
false	declaration is bad, the error message is displayed if !PT_SIL

THREAD_SAFE int convert_pt_flags_to_hti ( int  pt_flags )

inline

Convert Type parsing flags to Type formatting flags.

Type parsing flags lesser than 0x10 don't have stable meaning and will be ignored (more on these flags can be seen in idc.idc)

idaman int ida_export parse_decls	(	til_t *	til,
		const char *	input,
		printer_t *	printer,
		int	hti_flags
	)

Parse many declarations and store them in a til.

If there are any errors, they will be printed using 'printer'. This function uses default include path and predefined macros from the database settings. It always uses the HTI_DCL bit.

Parameters

til	type library to store the result
input	input string or file name (see hti_flags)
printer	function to output error messages (use msg or NULL or your own callback)
hti_flags	combination of Type formatting flags

Returns

number of errors, 0 means ok.

idaman bool ida_export print_type	(	qstring *	out,
		ea_t	ea,
		int	prtype_flags
	)

Get type declaration for the specified address.

Parameters

out	output buffer
ea	address
prtype_flags	combination of Type printing flags

Returns

success
