Function Documentation

set_segm_name()

idaman int ida_export set_segm_name	(	segment_t *	s,
		const char *	name,
		int	flags = 0
	)

Rename segment.

The new name is validated (see validate_name). A segment always has a name. If you hadn't specified a name, the kernel will assign it "seg###" name where ### is segment number.

Parameters

s	pointer to segment (may be nullptr)
name	new segment name
flags	ADDSEG_IDBENC or 0

Return values

1	ok, name is good and segment is renamed
0	failure, name is bad or segment is nullptr

get_segm_name()

idaman ssize_t ida_export get_segm_name	(	qstring *	buf,
		const segment_t *	s,
		int	flags = 0
	)

Get true segment name by pointer to segment.

Parameters

buf	output buffer. cannot be nullptr
s	pointer to segment
flags	0-return name as is; 1-substitute bad symbols with _ 1 corresponds to GN_VISIBLE

Returns

size of segment name (-1 if s==nullptr)

get_visible_segm_name()

ssize_t idaapi get_visible_segm_name ( qstring *  buf, const segment_t *  s  )

inline

Get segment name by pointer to segment.

Parameters

buf	output buffer. cannot be nullptr
s	pointer to segment

Returns

size of segment name (-1 if s==nullptr)

get_segm_expr()

ssize_t get_segm_expr	(	qstring *	buf,
		ea_t	from,
		sel_t	sel
	)

Get colored segment name expression in the form (segname + displacement).

Parameters

buf	output buffer to hold segment expression
from	linear address of instruction operand or data referring to the name. This address will be used to get fixup information, so it should point to exact position of operand in the instruction.
sel	value to convert to segment expression

Returns

size of segment expression or -1
