Inherited from object: __delattr__, __format__, __getattribute__, __hash__, __new__, __reduce__, __reduce_ex__, __setattr__, __sizeof__, __str__, __subclasshook__

Properties
  thisown
The membership flag

Inherited from object: __class__

Method Details

__init__(self, _flags=0)
(Constructor)

 

x.__init__(...) initializes x; see help(type(x)) for signature

Returns: IDP_Hooks
Overrides: object.__init__

__repr__(self)
(Representation operator)

 

repr(x)

Overrides: object.__repr__
(inherited documentation)

ev_ana_insn(self, out)

 

Analyzes and decodes an instruction at insn.ea

  • insn.itype must be set >= idaapi.CUSTOM_CMD_ITYPE
  • insn.size must be set to the instruction length
Returns: bool
Boolean
  • False if the instruction is not recognized
  • True if the instruction was decoded. 'insn' should be filled in that case.

ev_assemble(self, ea, cs, ip, use32, line)

 

Assembles an instruction

Parameters:
  • ea - linear address of instruction
  • cs - cs of instruction
  • ip - ip of instruction
  • use32 - is 32bit segment?
  • line - line to assemble
Returns: PyObject *
- None to let the underlying processor module assemble the line
  • or a string containing the assembled buffer

ev_emu_insn(self, insn)

 

Emulate instruction, create cross-references, plan to analyze subsequent instructions, modify flags etc. Upon entrance to this function all information about the instruction is in 'insn' structure.

Returns: bool
Boolean (whether this instruction has been emulated or not)

ev_is_call_insn(self, insn)

 

Is the instruction a "call"?

Parameters:
  • insn - instruction
Returns: int
0-unknown, 1-yes, -1-no

ev_is_ret_insn(self, insn, strict)

 

Is the instruction a "return"?

Parameters:
  • insn - instruction
  • strict - - True: report only ret instructions False: include instructions like "leave" which begins the function epilog
Returns: int
0-unknown, 1-yes, -1-no

ev_is_sane_insn(self, insn, no_crefs)

 

is the instruction sane for the current file type?

Parameters:
  • insn - the instruction
  • no_crefs -
    • 1: the instruction has no code refs to it. ida just tries to convert unexplored bytes to an instruction (but there is no other reason to convert them into an instruction)
    • 0: the instruction is created because of some coderef, user request or another weighty reason.
Returns: int
>=0-ok, <0-no, the instruction isn't likely to appear in the program

ev_may_be_func(self, insn, state)

 

Can a function start here?

Parameters:
  • insn - the instruction
  • state - autoanalysis phase 0: creating functions 1: creating chunks
Returns: int
integer (probability 0..100)

ev_out_insn(self, outctx)

 

Outputs the instruction defined in 'ctx.insn'

Returns: bool
Boolean (whether this instruction can be outputted or not)

ev_out_operand(self, outctx, op)

 

Notification to generate operand text. If False was returned, then the standard operand output function will be called.

this notification may use out_...() functions to form the operand text

Returns: bool
Boolean (whether the operand has been outputted or not)

ev_rename(self, ea, new_name)

 

The kernel is going to rename a byte.

Parameters:
  • ea - Address
  • new_name - The new name
Returns: int
  • If returns value <0, then the kernel should not rename it. See also the 'renamed' event

ev_undefine(self, ea)

 

An item in the database (insn or data) is being deleted

Parameters:
  • ea - Address
Returns: int
  • 1 - do not delete srranges at the item end
  • 0 - srranges can be deleted

hook(self)

 

Creates an IDP hook

Returns: bool
Boolean true on success

unhook(self)

 

Removes the IDP hook

Returns: bool
Boolean true on success
