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)
