SYNTAX
#include <sys/types.h>
DESCRIPTION
The data types defined in the include file are used in DG/UX
system code; some data of these types are accessible to user
code:
typedef struct { int r[1]; } * physadr;
typedef long daddr_t;
typedef char * caddr_t;
typedef unsigned int uint;
typedef unsigned short ushort;
typedef unsigned long u_long;
typedef u_long ino_t;
typedef short cnt_t;
typedef long time_t;
typedef int label_t[10];
typedef short dev_t;
typedef long off_t;
typedef long paddr_t;
typedef long key_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
GMT, 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.
