This is a repost from March 10, I did not get any answer, maybe this time I
will be lucky.


With CW 9.3 in C,

Let say I have a typedef of a struct (fooStruct)

I declare 2 structs:
fooStruct udsStructA;
fooStruct udsStructB;

I can copy the struct content with this:
udsStructA=udsStructB;

the assembly looks like:
00000068: 41ED 0000          lea       udsStructB,a0
0000006C: 43ED 0000          lea       udsStructA,a1
00000070: 303C 0359          move.w    #857,d0
00000074: 22D8               move.l    (a0)+,(a1)+
00000076: 51C8 FFFC          dbra      d0,*-2         ; 0x00000074


and with that:
MemMove(&udsStructA,&udsStructB,sizeof(fooStruct));

the assembly looks like:
0000007A: 4878 0D68          pea       0x00000d68
0000007E: 486D 0000          pea       udsStructB
00000082: 486D 0000          pea       udsStructA
00000086: 4E4F               trap      #15
00000088: A026               sysTrapMemMove

My assembly knowleage date from the 8080, 6802 days so I am a bit out of
date on 68K assembly ;-)

Which way is the best way to do this?

Thanks
