Function Documentation

create_data()

idaman bool ida_export create_data	(	ea_t	ea,
		flags64_t	dataflag,
		asize_t	size,
		tid_t	tid
	)

Convert to data (byte, word, dword, etc).

This function may be used to create arrays.

Parameters

ea	linear address
dataflag	type of data. Value of function byte_flag(), word_flag(), etc.
size	size of array in bytes. should be divisible by the size of one item of the specified type. for variable sized items it can be specified as 0, and the kernel will try to calculate the size.
tid	type id. If the specified type is a structure, then tid is structure id. Otherwise should be BADNODE.

Returns

success

create_align()

idaman bool ida_export create_align	(	ea_t	ea,
		asize_t	length,
		int	alignment
	)

Create an alignment item.

Parameters

ea	linear address
length	size of the item in bytes. 0 means to infer from ALIGNMENT
alignment	alignment exponent. Example: 3 means align to 8 bytes. 0 means to infer from LENGTH It is forbidden to specify both LENGTH and ALIGNMENT as 0.

Returns

success

calc_min_align()

idaman int ida_export calc_min_align

(

asize_t

length

)

Calculate the minimal possible alignment exponent.

Parameters

length

size of the item in bytes.

Returns

a value in the 1..32 range

calc_max_align()

idaman int ida_export calc_max_align

(

ea_t

endea

)

Calculate the maximal possible alignment exponent.

Parameters

endea

end address of the alignment item.

Returns

a value in the 0..32 range

calc_def_align()

idaman int ida_export calc_def_align	(	ea_t	ea,
		int	mina,
		int	maxa
	)

Calculate the default alignment exponent.

Parameters

ea	linear address
mina	minimal possible alignment exponent.
maxa	minimal possible alignment exponent.
