Hi,
I'm using the following function to join 2 char (byte) into one short on
a 32 bit X86 platform:
unsigned short joinUnsigShort(unsigned char a,unsigned char b)
{
unsigned short val = 0;
val = a;
val <<= 8;
val |= b;
return val;
}
Will this also work if compiled on a PowerPC? Are there better ways to
do it?
It will do what it says. Whether it will do what you want depends on
exactly what you want, which you haven't quite told us.
There are many possible ways to join two chars into a short. What
exactly are you trying to accomplish? Do you want the value of "a" in
the high-order bits of the result? Do you want it in the leftmost
(lowest address) portion of the result?

We must do something. This is something. Therefore, we must do this.
