fixup_handler_t Struct Reference

Detailed Description

Implements the core behavior of a custom fixup.

Public Attributes

uint8	width
	number of significant bits before shifting
uint8	shift

uint8	rsrv4
uint32	reftype
	reference info type and flags, std_apply() produces an offset of this type
bool(idaapi *	apply )(const fixup_handler_t *fh, ea_t item_ea, ea_t fixup_ea, int opnum, bool is_macro, const fixup_data_t &fd)
	Apply a fixup: take it into account while analyzing the file. More...
uval_t(idaapi *	get_value )(const fixup_handler_t *fh, ea_t ea)
	Get the operand value. More...

Member Data Documentation

apply

bool(idaapi * fixup_handler_t::apply) (const fixup_handler_t *fh, ea_t item_ea, ea_t fixup_ea, int opnum, bool is_macro, const fixup_data_t &fd)

Apply a fixup: take it into account while analyzing the file.

Usually it consists of converting the operand into an offset expression.

See also

apply_fixup() If this callback is not specified then std_apply() is used.

get_value

uval_t(idaapi * fixup_handler_t::get_value) (const fixup_handler_t *fh, ea_t ea)

Get the operand value.

This callback is called from get_fixup_value().

See also

get_fixup_value() If this callback is not specified then std_get_value() is used.

patch_value

bool(idaapi * fixup_handler_t::patch_value) (const fixup_handler_t *fh, ea_t ea, const fixup_data_t &fd)

Patch the fixup bytes.

This callback is called from patch_fixup_value() or after changing the fixup (e.g. after it was moved from one location to another). If this callback is not specified then std_patch_value() is used.

See also

patch_fixup_value()

Return values

false

the fixup bytes do not fit. The database is changed even in this case.
