    This is the wholesale:

    typedef unsigned long long u64;

    /* usable for char, short int, and int */
    #define set_to_max(a) do { \
    u64 __val_max = ((u64) 1 << (sizeof(a) * 8)) - 1; \
    a = __val_max; \
    if ((u64) a != __val_max) \
    a = __val_max / 2; \
    } while(0)

    #define set_to_min(a) do { \
    set_to_max(a); \
    a++; \
    } while(0)
