byte reversal

[Jemellie]

First off, I am using CVI LabWindows version 7.1.  How do I reverse the byte order? I am receiving the mirror image of the data being sent to me over a TCP connection.  for example, if the data being sent (in hexadecimal) is 01020304, the data that I will receive is 40302010.  How do I fix this problem?



Thank You,

Hi Jemellie,


short SwapBytes (short data)
{
char temp;

union {
short data;
struct {
char byte_1;
char byte_2;
} order;
} swap;

swap. data = data;
temp = swap.order.byte_1;
swap.order.byte_1 = swap.order.byte_2;
swap.order.byte_2 = temp;
return swap.data;
}

Just call this function with the two byte value you want to swap the byte
order. The return value is the result.
