Detailed Description

Contains functions that deal with individual byte characteristics.

Each byte of the disassembled program is represented by a 32-bit value. We will call this value 'flags'. The structure of the flags is here.

You are not allowed to inspect individual bits of flags and modify them directly. Use special functions to inspect and/or modify flags.

Flags are kept in a virtual array file (*.id1). Addresses (ea) are all 32-bit (or 64-bit) quantities.

Macro Definition Documentation

◆ GFE_VALUE

#define GFE_VALUE 0x0001

get flags with FF_IVL & MS_VAL.

It is much slower under remote debugging because the kernel needs to read the process memory.

◆ GFE_IDB_VALUE

#define GFE_IDB_VALUE 0x0002

get flags with FF_IVL & MS_VAL.

but never use the debugger memory.

◆ GET_ITEM_HEAD_BODY

#define GET_ITEM_HEAD_BODY

Value:

  if ( is_tail(get_flags(ea)) ) \
    ea = prev_not_tail(ea);     \
  return ea;

Function Documentation

◆ enable_flags()

idaman error_t ida_export enable_flags	(	ea_t	start_ea,
		ea_t	end_ea,
		storage_type_t	stt
	)

Allocate flags for address range.

This function does not change the storage type of existing ranges. Exit with an error message if not enough disk space.

Parameters

start_ea	should be lower than end_ea.
end_ea	does not belong to the range.
stt	storage_type_t

Returns: 0 if ok, otherwise an error code

◆ disable_flags()

idaman error_t ida_export disable_flags	(	ea_t	start_ea,
		ea_t	end_ea
	)

Deallocate flags for address range.

Exit with an error message if not enough disk space (this may occur too).

Parameters

start_ea	should be lower than end_ea.
end_ea	does not belong to the range.

Returns: 0 if ok, otherwise return error code

◆ change_storage_type()

idaman error_t ida_export change_storage_type	(	ea_t	start_ea,
		ea_t	end_ea,
		storage_type_t	stt
	)

Change flag storage type for address range.

Parameters

start_ea	should be lower than end_ea.
end_ea	does not belong to the range.
stt	storage_type_t

Returns: error code

◆ next_addr()

idaman ea_t ida_export next_addr ( ea_t ea )

Get next address in the program (i.e.

next address which has flags).

Returns: BADADDR if no such address exist.

◆ prev_addr()

idaman ea_t ida_export prev_addr ( ea_t ea )

Get previous address in the program.

Returns: BADADDR if no such address exist.

◆ next_chunk()

idaman ea_t ida_export next_chunk ( ea_t ea )

Get the first address of next contiguous chunk in the program.

Returns: BADADDR if next chunk doesn't exist.

◆ prev_chunk()

idaman ea_t ida_export prev_chunk ( ea_t ea )

Get the last address of previous contiguous chunk in the program.

Returns: BADADDR if previous chunk doesn't exist.

◆ chunk_start()

idaman ea_t ida_export chunk_start ( ea_t ea )

Get start of the contiguous address block containing 'ea'.

Returns: BADADDR if 'ea' doesn't belong to the program.

◆ chunk_size()

idaman asize_t ida_export chunk_size ( ea_t ea )

Get size of the contiguous address block containing 'ea'.

Returns: 0 if 'ea' doesn't belong to the program.

◆ find_free_chunk()

idaman ea_t ida_export find_free_chunk	(	ea_t	start,
		asize_t	size,
		asize_t	alignment
	)

Search for a hole in the addressing space of the program.

		int	flags = `0`
	)

Get contents of string literal, as UTF-8-encoded codepoints.

This function returns the displayed part of the string It works even if the string has not been created in the database yet.

If 'len' is size_t(-1), it will be computed like so:

if a string literal is present at 'ea', get_item_size() * bytesize(ea) will be used
otherwise, get_max_strlit_length(..., ALOPT_IGNHEADS) will be used

About 'maxcps': this specifies a limit to the number of codepoints, not bytes in the UTF-8 output buffer. So for example although U+4e12 will use 3 bytes in the output buffer, it still counts as only 1 character – unless STRCONV_ESCAPE is used. If 'STRCONV_ESCAPE' is used, U+4e12 will be converted to the string "\u4E12", and will use 6 bytes in the output buffer and also count as 6 codepoints.

If 'STRCONV_REPLCHAR', any undecodable byte will re represented as U+FFFD, occupy 3 bytes in the output buffer, and count for 1 codepoint.

Parameters

[out]	utf8	output buffer
[in]	ea	linear address of the string
[in]	len	length of the string, in octets (octet=8bit)
[in]	type	type of the string. one of String type codes
[in,out]	maxcps	maximum length of codepoints, after possible escaping, in output buffer (not counting terminating zero) on exit, will be set to 0 if string got truncated can be nullptr if not needed

length	length of the new item in bytes
flags	if not 0, then the kernel will ignore the data types specified by the flags and destroy them. For example: 1000 dw 5 1002 db 5 ; undef 1003 db 5 ; undef 1004 dw 5 1006 dd 5 can_define_item(1000, 6, 0) - false because of dw at 1004 can_define_item(1000, 6, word_flag()) - true, word at 1004 is destroyed

Returns: 1-yes, 0-no

This function may return 0 if:

a new item would cross segment boundaries
a new item would overlap with existing items (except items specified by 'flags')

◆ register_custom_data_type()

idaman int ida_export register_custom_data_type ( const data_type_t * dtinfo )

Register a new data type.

Parameters

dtinfo description of the new data type

Returns: > 0 : id of the new custom data type, < 0 : error when the custom data type with the same name has already been registered

Note: dtid 0 is reserved for built-in data types.

◆ unregister_custom_data_type()

idaman bool ida_export unregister_custom_data_type ( int dtid )

Unregister a data type.

When the idb is closed, all custom data types are automatically unregistered, but since it happens too late (plugin modules could already be unloaded) one has to unregister custom data types explicitly. The ids of unregistered custom data types remain allocated and when the same name is reused to register a custom data type, it will get assigned the same id.

Parameters

dtid	data type to unregister

Return values

true	ok
false	no such dtid

◆ register_custom_data_format()

idaman int ida_export register_custom_data_format ( const data_format_t * dtform )

Register a new data format.

Parameters

dtform description of the new data format

Returns: > 0 : id of the new custom data format, < 0 : error when the custom data format with the same name has already been registered to the data type

Note: dfid 0 is unused.

◆ unregister_custom_data_format()

idaman bool ida_export unregister_custom_data_format ( int dfid )

◆ detach_custom_data_format()

idaman bool ida_export detach_custom_data_format	(	int	dtid,

		qstring *	errbuf = `nullptr`
	)

Convert user-specified binary string to internal representation.

The 'in' parameter contains space-separated tokens:

- numbers (numeric base is determined by 'radix')
    - if value of number fits a byte, it is considered as a byte
    - if value of number fits a word, it is considered as 2 bytes
    - if value of number fits a dword,it is considered as 4 bytes
- "..." string constants
- 'x'  single-character constants
- ?    variable bytes

Note that string constants are surrounded with double quotes.

Here are a few examples (assuming base 16):

CD 21          - bytes 0xCD, 0x21
21CD           - bytes 0xCD, 0x21 (little endian ) or 0x21, 0xCD (big-endian)
"Hello", 0     - the null terminated string "Hello"
L"Hello"       - 'H', 0, 'e', 0, 'l', 0, 'l', 0, 'o', 0
B8 ? ? ? ? 90  - byte 0xB8, 4 bytes with any value, byte 0x90

Parameters

[out]	out	a vector of compiled binary patterns, for use with bin_search2()
	ea	linear address to convert for (the conversion depends on the address, because the number of bits in a byte depend on the segment type)
	in	input text string
	radix	numeric base of numbers (8,10,16)
	strlits_encoding	the target encoding into which the string literals present in 'in', should be encoded. Can be any from [1, get_encoding_qty()), or the special values PBSENC_*
	errbuf	error buffer (can be nullptr)

Returns: false either in case of parsing error, or if at least one requested target encoding couldn't encode the string literals present in "in".
