function InterceptCreate(const TargetProc, InterceptProc: Pointer): Pointer;
{ Redirects the procedure TargetProc to InterceptProc. Returns the address of a
trampoline function, which can be used to call the original routine from
your Intercept. Also, the trampoline function must be passed to the
InterceptRemove function to restore the original routine again. The Intercept
and trampoline routines must have the exact same signature as TargetProc for
the Intercept to work. Example:
var
TrampolineMessageBox: function(hWnd: HWND; lpText, lpCaption: PChar;
uType: UINT): Integer; stdcall;
function InterceptMessageBox(hWnd: HWND; lpText, lpCaption: PChar;
uType: UINT): Integer; stdcall;
var
S: String;
begin
S := UpperCase(lpText);
Result := TrampolineMessageBox(hWnd,PChar(S),lpCaption,uType);
end;
@TrampolineMessageBox := InterceptCreate(@MessageBox,@InterceptMessageBox);
MessageBox(0,'Intercept test','Test',MB_OK);
// Will display the message 'Intercept test' in upper case
InterceptRemove(@TrampolineMessageBox,@InterceptMessageBox);
MessageBox(0,'Intercept test','Test',MB_OK);
// Will display the message 'Intercept test' in original case }
function InterceptRemove(var Trampoline: Pointer; const InterceptProc: Pointer): Boolean;
{ Restores the Intercept. You must pass the trampoline as returned by the
InterceptCreate function and the Intercept routine. This trampoline will be freed
and set to nil }

should be large enough to accomodate at least 5 bytes from the original
routine, and 5 bytes for an unconditional JMP instruction. A single
assembly instruction can take up 17 bytes: up to 4 bytes for an instruction
prefix + up to 3 bytes for the instruction opcode + 1 optional ModR/M byte
+ 1 optional SIB-byte + up to 4 address displacement bytes + up to 4
immediate data bytes (see Intel's IA-32 instruction reference for details).
Since at least 5 bytes from the original routine have to be copied to the
trampoline, and the fifth byte could start a new 17-byte instruction, this
means a maximum of 4+17=21 bytes could be needed. Including the 5 bytes for
an unconditional JMP, we should allocate 26 bytes minimum. We use 32 bytes
here to be on the safe side. }

source instruction and Dst to the already copied destination instruction.

offset from the OpCode where the relative target is located.
Example:
Src: $00005000 jmp -$1000
At address $00005000 is an instruction that jumps $1000 bytes backwards,
that is to address $00004000. When this instruction is copied to Dst
at address $00007000:
Dst: $00007000 jmp -$1000
