You can force the compiler to do it differently with something like struct A { unsigned int a; unsigned int b; short int c; } __attribute__((packed)); or you can control the alignment of your structure or your structure members with __attribute__((aligned(n))), n being a power of 2. But do you really need that? Compilers usually align the data on purpose... Bengt
