Detailed Description

Assembly level enum management.

Enums and bitfields are represented as enum_t.

add_enum()

idaman enum_t ida_export add_enum	(	size_t	idx,

		flags64_t	flag
	)

Add new enum type.

• if idx==BADADDR then add as the last idx
• if name==nullptr then generate a unique name "enum_%d"

set_enum_idx()

idaman bool ida_export set_enum_idx	(	enum_t	id,
		size_t	idx
	)

Set serial number of enum.

Also see get_enum_idx().

idaman int ida_export add_enum_member	(	enum_t	id,
		const char *	name,
		uval_t	value,
		bmask_t	bmask = DEFMASK
	)

Add member to enum type.

Returns

0 if ok, otherwise one of Add enum member result codes
