types(5)types(5)NAMEtypes - primitive system data typesSYNOPSIS
#include <sys/types.h>
DESCRIPTION
The data types defined in types.h are used in UNIX System code. Some
data of these types are accessible to user code:
typedef struct { int r[1]; } *physadr;
typedef long clock_t;
typedef long daddr_t;
typedef long pgno_t;
typedef char * addr_t;
typedef char * caddr_t;
typedef unsigned char unchar;
typedef unsigned short ushort;
typedef unsigned int uint;
typedef unsigned long ulong;
typedef unsigned long ino_t;
typedef long uid_t;
typedef long gid_t;
typedef unsigned long nlink_t;
typedef unsigned long mode_t;
typedef short cnt_t;
typedef long time_t;
typedef long swblk_t;
typedef int label_t[12];
typedef unsigned long dev_t;
typedef long off_t;
typedef long pid_t;
typedef long paddr_t;
typedef int key_t;
typedef unsigned char use_t;
typedef short sysid_t;
typedef short index_t;
typedef unsigned int lock_t;
typedef signed char cpuid_t;
typedef unsigned int size_t;
typedef int ssize_t;
typedef long clock_t;
typedef long pid_t;
typedef long id_t;
typedef long hostid_t;
The form daddr_t is used for disk addresses except in an i-node on disk,
see fs(4). Times are encoded in seconds since 00:00:00 UTC, January 1,
1970. The major and minor parts of a device code specify kind and unit
number of a device and are installation-dependent. Offsets are measured
in bytes from the beginning of a file. The label_t variables are used to

save the processor state while another process is running.
