In order to keep the kernel clean and small, it uses very basic functions only:. | |

typedef unsigned char u_char |
Unsigned 8-bit value.
typedef unsigned short u_short |
Unsigned 16-bit value.
typedef unsigned int u_int |
typedef unsigned long u_long |
Unsigned 32-bit value.
typedef unsigned long long u_longlong |
typedef unsigned short ureg_t |
Unsigned register type.
The size of this type is equal to the size of a register, the hardware datapath or whatever might fit to give optimum performance for values from 0 to 255.
Typically 8 bit CPUs will use unsigned characters, 16 bit CPUs will use unsigned shorts etc.
