File attribute constants

Syntax

#include<io.h>

Remarks

These constants specify the current attributes of the file or directory specified by the function.

The attributes are represented by the following manifest constants:

Constant	Description
_A_ARCH	Archive. Set whenever the file is changed, and cleared by the BACKUP command. Value: 0x20
_A_HIDDEN	Hidden file. Not normally seen with the DIR command, unless the /AH option is used. Returns information about both normal files and files with this attribute. Value: 0x02
_A_NORMAL	Normal. File can be read or written to without restriction. Value: 0x00
_A_RDONLY	Read-only. File can't be opened for writing, and a file with the same name can't be created. Value: 0x01
_A_SUBDIR	Subdirectory. Value: 0x10
_A_SYSTEM	System file. Not normally seen with the DIR command, unless the /AS option is used. Value: 0x04

Multiple constants can be combined with the OR operator (|).
