Enumeration Type Documentation

◆ sub_metatype

enum sub_metatype

Specializations of the core meta-types. Each enumeration is associated with a specific type_metatype. Ordering is important: The lower the number, the more specific the data-type, affecting propagation.

Enumerator
SUB_VOID	Compare as a TYPE_VOID.
SUB_SPACEBASE	Compare as a TYPE_SPACEBASE.
SUB_UNKNOWN	Compare as a TYPE_UNKNOWN.
SUB_INT_CHAR	Signed 1-byte character, sub-type of TYPE_INT.
SUB_UINT_CHAR	Unsigned 1-byte character, sub-type of TYPE_UINT.
SUB_INT_PLAIN	Compare as a plain TYPE_INT.
SUB_UINT_PLAIN	Compare as a plain TYPE_UINT.
SUB_INT_ENUM	Signed enum, sub-type of TYPE_INT.
SUB_UINT_ENUM	Unsigned enum, sub-type of TYPE_UINT.
SUB_INT_UNICODE	Signed wide character, sub-type of TYPE_INT.
SUB_UINT_UNICODE	Unsigned wide character, sub-type of TYPE_UINT.
SUB_BOOL	Compare as TYPE_BOOL.
SUB_CODE	Compare as TYPE_CODE.
SUB_FLOAT	Compare as TYPE_FLOAT.
SUB_PTRREL_UNK	Pointer to unknown field of struct, sub-type of TYPE_PTR.
SUB_PTR	Compare as TYPE_PTR.
SUB_PTRREL	Pointer relative to another data-type, sub-type of TYPE_PTR.
SUB_PTR_STRUCT	Pointer into struct, sub-type of TYPE_PTR.
SUB_ARRAY	Compare as TYPE_ARRAY.
SUB_PARTIALSTRUCT	Compare as TYPE_PARTIALSTRUCT.
SUB_STRUCT	Compare as TYPE_STRUCT.

◆ 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.

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_PTRREL	Pointer relative to another data-type (specialization of TYPE_PTR)
TYPE_ARRAY	Array data-type, made up of a sequence of "element" datatype.
TYPE_PARTIALSTRUCT	Part of a structure, stored separately from the whole.
TYPE_STRUCT	Structure data-type, made up of component datatypes.
