Detailed Description

Classes for describing and printing data-types.

Enumeration Type Documentation

type_metatype

enum type_metatype

The core meta-types supported by the decompiler. These are sizeless templates for the elements making up the type algebra. Ordering is important: The lower the number, the more specific the type, in calculations involving the generality of a type.

Enumerator
TYPE_VOID	Standard "void" type, absence of type.
TYPE_SPACEBASE	Placeholder for symbol/type look-up calculations.
TYPE_UNKNOWN	An unknown low-level type. Treated as an unsigned integer.
TYPE_INT	Signed integer. Signed is considered less specific than unsigned in C.
TYPE_UINT	Unsigned integer.
TYPE_BOOL	Boolean.
TYPE_CODE	Data is actual executable code.
TYPE_FLOAT	Floating-point.
TYPE_PTR	Pointer data-type.
TYPE_ARRAY	Array data-type, made up of a sequence of "element" datatype.
TYPE_STRUCT	Structure data-type, made up of component datatypes.

Function Documentation

metatype2string()

void metatype2string	(	type_metatype	metatype,
		string &	res
	)

Convert type meta-type to name.

Convert a type meta-type into the string name of the meta-type

Parameters

metatype	is the encoded type meta-type
res	will hold the resulting string

References TYPE_ARRAY, TYPE_BOOL, TYPE_CODE, TYPE_FLOAT, TYPE_INT, TYPE_PTR, TYPE_SPACEBASE, TYPE_STRUCT, TYPE_UINT, TYPE_UNKNOWN, and TYPE_VOID.

print_data()

void print_data	(	ostream &	s,
		uint1 *	buffer,
		int4	size,
		const Address &	baseaddr
	)

Print a hex dump of a data buffer to stream.

Display an array of bytes as a hex dump at a given address. Each line displays an address and 16 bytes in hexadecimal

Parameters

s	is the stream to write to
buffer	is a pointer to the bytes
size	is the number of bytes
baseaddr	is the address of the first byte in the buffer

References Address::getOffset().

string2metatype()

type_metatype string2metatype

(

const string &

metastring

)

Convert string to type meta-type.

Given a string description of a type meta-type. Return the meta-type.

Parameters

metastring

is the description of the meta-type

Returns

the encoded type meta-type
