Member Data Documentation

asize_t func_t::frsize

size of local variables part of frame in bytes.

If FUNC_FRAME is set and fpd==0, the frame pointer (EBP) is assumed to point to the top of the local variables range.

ushort func_t::frregs

size of saved registers in frame.

This range is immediately above the local variables range.

asize_t func_t::fpd

frame pointer delta.

(usually 0, i.e. realBP==typicalBP) use update_fpd() to modify it.

stkpnt_t* func_t::points

array of SP change points.

use ...stkpnt...() functions to access this array.

regvar_t* func_t::regvars

array of register variables.

this array is sorted by: start_ea. use ...regvar...() functions to access this array.

llabel_t* func_t::llabels

local labels.

this array is sorted by ea. use ...llabel...() functions to access this array.

regarg_t* func_t::regargs

unsorted array of register arguments.

use ...regarg...() functions to access this array.

range_t* func_t::tails

array of tails, sorted by ea.

use func_tail_iterator_t to access function tails.

ea_t* func_t::referers

array of referers (function start addresses).

use func_parent_iterator_t to access the referers.
