Convert address to code to real address of code.
Unit
ELowLevel
Syntax
Code (Delphi)
|
function ConvertAddress(
const AAddr: Pointer
): Pointer;
|
Parameters
AAddr [in]
Address to code. Usually points to routine.
Return value
Adjusted address to code. See remarks. Can be the same value as AAddr.
Remarks
This routine is used for hooks.
If you have an address to routine - it can points to code itself or to JMP instruction to code. Typical example is import table.
This function takes address and checks if there is a JMP instruction at this address.
| • | If there is no JMP - then function returns value unchanged. |
| • | If there is JMP opcode - then function returns target of that JMP. |
Function doesn't raise access violation in case of unavailable memory.
Examples
Code (Delphi)
|
var
P: Pointer;
begin
P := @GetWindowText; // P can point to routine itself or stub with JMP
P := ConvertAddr(P); // now P points to routine itself
end;
