The size of types such as int, long, and long long isn't strictly defined in C. If you want to specify integers of specific byte sizes, you should #include stdint.h and use int32_t, uint16_t, etc.

Your 4 byte value will be an unsigned long and the 2 byte value will be an unsigned short.

I'm not sure this is what you want but.. does this work for you ?

struct data {
    uint32_t int4;
    uint16_t int2;
};
