Detailed Description

Describes a program segment.

Member Function Documentation

is_ephemeral_segm()

bool segment_t::is_ephemeral_segm ( void  ) const

inline

Ephemeral segments are not analyzed automatically (no flirt, no functions unless required, etc).

Most likely these segments will be destroyed at the end of the debugging session unless the user changes their status.

update()

bool segment_t::update ( void  )

inline

Update segment information.

You must call this function after modification of segment characteristics. Note that not all fields of segment structure may be modified directly, there are special functions to modify some fields.

Returns

success

Member Data Documentation

orgbase

uval_t segment_t::orgbase

this field is IDP dependent.

you may keep your information about the segment here

bitness

uchar segment_t::bitness

Number of bits in the segment addressing.

• 0: 16 bits
• 1: 32 bits
• 2: 64 bits

sel

sel_t segment_t::sel

segment selector - should be unique.

You can't change this field after creating the segment. Exception: 16bit OMF files may have several segments with the same selector, but this is not good (no way to denote a segment exactly) so it should be fixed in the future.

defsr

sel_t segment_t::defsr[SREG_NUM]

default segment register values.

first element of this array keeps information about value of processor_t::reg_first_sreg

type

uchar segment_t::type

segment type (see Segment types).

The kernel treats different segment types differently. Segments marked with '*' contain no instructions or data and are not declared as 'segments' in the disassembly.
