NAME
types - system data types
SYNOPSIS
#include <sys/types.h>
DESCRIPTION
The file <sys/types.h> contains defined data types used throughout the
system.

typedef unsigned long clock_t;
typedef unsigned int size_t;
typedef int ssize_t;
typedef long time_t;
/* Virtual memory objects. */
typedef unsigned long vm_offset_t;
typedef unsigned long vm_size_t;
/* The longest/most efficient integer register type. */
typedef int32_t register_t;
/* Architecture independent types. */
/* Basic integral types of exactly the implied number of bits. */
typedef __signed char int8_t;
typedef unsigned char u_int8_t;
typedef short int16_t;
typedef unsigned short u_int16_t;
typedef int int32_t;
