Well, but just point a little thing about it, and help you see some of
these points I'm starting to think right now (the first time I ever
think about it):
If you replaced the semicolon between second and third, that's the
second semicolon, you write:
for(i =3D 0; cp =3D msg, *(cp + i); i++)
It would be better
for(i =3D 0, cp =3D msg; *(cp + i); i++)
since in the body of the for loop you're not modifying the value of cp
(if you do so and want the second statement form then the first would be
better, so it would restore cp =3D msg for each cycle), but here you don'=
t
modify it, so it willl be constant for all the loops.
The for loops work this way: The first field is executed in the first
place the first cycle and no more, the second field is executed once for
every loop at the first place (or after the first if it's the first
loop) and the third loop executes at the last moment for every cycle.
If you use the first form you're doing the assigment every cycle, which
would give a performance penalty (I don't know at all how much it can be
noticed or not), with the second you're doing it just the first time and
no more, which is the best since you don't need repeat it.
