types(FP)

types -- primitive system data types

Syntax

#include <sys/types.h>

Description

The data types defined in the include file <sys/types.h> are used in UNIX system code; some of these data types are accessible to user code.

The form daddr_t is used for disk addresses except in an inode on disk (see filesystem(FP)). 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.
