Function Details

create_switch_xrefs(insn_ea, py_swi)

This function creates xrefs from the indirect jump.

Usually there is no need to call this function directly because the kernel will call it for switch tables

Note: Custom switch information are not supported yet.

Parameters:

insn_ea - address of the 'indirect jump' instruction
si - switch information

Returns: bool

Boolean

calc_switch_cases(insn_ea, py_swi)

Get information about a switch's cases.

The returned information can be used as follows:

    for idx in xrange(len(results.cases)):
        cur_case = results.cases[idx]
        for cidx in xrange(len(cur_case)):
            print "case: %d" % cur_case[cidx]
        print "  goto 0x%x" % results.targets[idx]

@param insn_ea: address of the 'indirect jump' instruction
@param si: switch information

@return: a structure with 2 members: 'cases', and 'targets'.

Returns: cases_and_targets_t

create_switch_table(insn_ea, py_swi)

Create switch table from the switch information

Parameters:

insn_ea - address of the 'indirect jump' instruction
si - switch information

Returns: bool

Boolean
