f_has_xref()

THREAD_SAFE bool idaapi f_has_xref ( flags64_t  f, void *    )

inline

Does the current byte have cross-references to it?

f_has_name()

THREAD_SAFE bool idaapi f_has_name ( flags64_t  f, void *    )

inline

Does the current byte have non-trivial (non-dummy) name?

f_has_dummy_name()

THREAD_SAFE bool idaapi f_has_dummy_name ( flags64_t  f, void *    )

inline

f_has_user_name()

THREAD_SAFE bool idaapi f_has_user_name ( flags64_t  F, void *    )

inline

is_invsign()

idaman bool ida_export is_invsign	(	ea_t	ea,
		flags64_t	F,
		int	n
	)

Should sign of n-th operand inverted during output?.

allowed values of n: 0-first operand, 1-other operands

toggle_sign()

idaman bool ida_export toggle_sign	(	ea_t	ea,
		int	n
	)

Toggle sign of n-th operand.

allowed values of n: 0-first operand, 1-other operands

is_bnot()

idaman bool ida_export is_bnot	(	ea_t	ea,
		flags64_t	F,
		int	n
	)

Should we negate the operand?.

asm_t::a_bnot should be defined in the idp module in order to work with this function

is_lzero()

idaman bool ida_export is_lzero	(	ea_t	ea,
		int	n
	)

Display leading zeroes? Display leading zeroes in operands.

The global switch for the leading zeroes is in idainfo::s_genflags Note: the leading zeroes doesn't work if for the target assembler octal numbers start with 0.

Parameters

ea	the item (insn/data) address
n	the operand number (0-first operand, 1-other operands)

Returns

success

set_lzero()

idaman bool ida_export set_lzero	(	ea_t	ea,
		int	n
	)

Set toggle lzero bit.

This function changes the display of leading zeroes for the specified operand. If the default is not to display leading zeroes, this function will display them and vice versa.

Parameters

ea	the item (insn/data) address
n	the operand number (0-first operand, 1-other operands)

Returns

success

clr_lzero()

idaman bool ida_export clr_lzero	(	ea_t	ea,
		int	n
	)

Clear toggle lzero bit.

This function reset the display of leading zeroes for the specified operand to the default. If the default is not to display leading zeroes, leading zeroes will not be displayed, as vice versa.

Parameters

ea	the item (insn/data) address
n	the operand number (0-first operand, 1-other operands)

Returns

success

toggle_lzero()

bool idaapi toggle_lzero ( ea_t  ea, int  n  )

inline

Toggle lzero bit.

Parameters

ea	the item (insn/data) address
n	the operand number (0-first operand, 1-other operands)

Returns

success
