Address Pointed to by Value in an Offset

[lmstearn]

Hi there, working with some code from here:

Code: Select all

SeekProc(stream, offset, type)
{
stream.Seek(offset)
VarSetCapacity(v,8)
bytesToRead := NumPut(0,v,0,type) - &v ; Numput returns the address to the "right" of item just written


bytesRead := stream.RawRead(v, bytesToRead)
if (v)
{
MsgBox, 4096, , % " Read failed"
return 0
}
else
{
if (offset)
	{
if (offset)
	{
	absOffset := NumGet(v, 0, type)
	stream.Seek(absOffset)
	Pos := stream.Tell()
	v := 0
	VarSetCapacity(v,8)
	bytesToRead := NumPut(0,v,0,type) - &v
	bytesRead := stream.RawRead(v, bytesToRead)
	}
	MsgBox, 4096, , % "NumGet(v, 0, type): " NumGet(v, 0, type) " v: " v " Curr. Pos: " Pos " bytesToRead: " bytesToRead " offset: " offset " absOffset: " absOffset
	return % NumGet(v, 0, type)
}
}

Is there some way to harness MemoryRead or the like to obtain a Location_Pointed_To_By_AddressOf(absOffset)?
Thanks for response.

Have you looked into possible Dll Calls that might be able to do that?

@JJohnston2: Yes, it's easiest to keep within the AHK file object. Think I know where the problem is:

Code: Select all

stream.Seek(&absOffset) ;

Is intended, but it's giving out of range addresses as it seems all that is required for Header reads is one byte addresses. So to strip the second half, reduce the VarSetCapacity.

[just me]

If the adresses/offsets are stored in x86 format (reversed byte order) you should consider to use ReadNum() instead of RawRead().
