The example below is not complete, you need to cast.
Is there any documentation on this?
would the following:
longv:=LEtoN(@buffer[5]);
be the same as:

Hi Mattias,
Is there an equivalent for
shortv:=buffer[5];
shortv+=buffer[6] shl 8;
Many thanks

The example below is not complete, you need to cast.
MyDouble:=LEtoN(PDouble(@buffer[5])^);
Use codejumping (find declaration) on LEtoN to see what variants exist.

Thanks Marc, I hadn't thought of doing that...
Thanks to all the guys

If I Blockread(F,buffer,4) with buffer being an array of byte, Is
there a routine in fpc/lazarus which will revers the bytes for me?
This is what I want:
longv:=buffer[0];

longv+=buffer[2] shl 16;
longv+=buffer[3] shl 24;
Is there a function
Great, thanks Andrew.
