What I want to do is:
char buffer[100];
char* message = buffer;
int index = 0;
buildHeader (&message[index]);
index += sizeof(HeaderType);
assembleData (&message[index]);
index += 10;
buildTrailer (&message[index]);
index += sizeof(TrailerType);
and return index as the size of the built message. As
you can see if sizeof (..) does not return the correct
value, it would mess up the content of the message and
also the return size. Of course, I can use 3 instead
of sizeof(HeaderType) or so but this is not really a
good programming practice since I may want to change
the structure of HeaderType and TrailerType later. On
the other hand I might also want to port existing code
built in other platforms to Palm OS and so if
sizeof(..) does not return the correct value ....my
feeling for CodeWarrior would be "!%$##@!#$%!@#%^$&*"
.
