Hi,
we are porting application from CodeWarrior to Xcode and encountered
problem:
Application built with CodeWarrior writes \r (0x0D) as end of line
while ported to Xcode Application writes \n (0x0A).
For example line endings are written by strcat(str, "\n"). As I understand this
string should add 0x0A to the end of string regardless of platform.
But when I debug code in CW I see that \r is really added to str
instead of \n. I tried to write strcat(str, "\r") - in this
case \n is really added to new_item. I also tried to write 0x0A - \n
is added to new_item which is correct. Seems that \r and \n
are preprocessed or specially handled by compiler.
http://web.mit.edu/macdev/Development/Documentation/www/devdoc/portPPC.html says that
MPW swaps the ASCII value of '\r' and '\n'. It does this because the
Mac uses '\r' to break lines but '\n' is commonly used for new lines
in standard C library routines such as printf....
So the question is how such swapping can be switched on in Xcode
build?
I think many developers already faced these problem.
