Various sizes on my computer and Arduino

Question

I am working on a backup time project by creating server code for the Arduino Duemilanove, but before testing this code on the controller, I test it on my own machine (MacBook based on OS X). I use ints in some places, and I am concerned that this will cause strange errors when the code is compiled and run on an Arduino Duemilanove, because Arduino treats ints as 2 bytes, and my macbook treats ints as 4 bytes. I'm not a hardcore C and C ++ programmer, so I'm a little worried about how an experienced programmer can handle this situation. Should I restrict the code with a typedef that includes my own definition and int that is limited to two bytes? Or is there another way?

Answer 1

It is best to use a title stdint.h. It defines typedefs that explicitly reference the signature and size of your variables. For example, a 16-bit unsigned integer is equal uint16_t. This is part of the C99 standard, so it is available almost everywhere. Cm:
