Variable Documentation

uint8_t const BOOTSIG0 = 0X55

Value for byte 510 of boot block or MBR

uint8_t const BOOTSIG1 = 0XAA

Value for byte 511 of boot block or MBR

uint8_t const DIR_ATT_ARCHIVE = 0X20

Old DOS archive bit for backup support

uint8_t const DIR_ATT_DEFINED_BITS = 0X3F

defined attribute bits

uint8_t const DIR_ATT_DIRECTORY = 0X10

Entry is for a directory

uint8_t const DIR_ATT_FILE_TYPE_MASK = (DIR_ATT_VOLUME_ID | DIR_ATT_DIRECTORY)

Mask for file/subdirectory tests

uint8_t const DIR_ATT_HIDDEN = 0X02

File should hidden in directory listings

uint8_t const DIR_ATT_LONG_NAME = 0X0F

Test value for long name entry. Test is (d->attributes & DIR_ATT_LONG_NAME_MASK) == DIR_ATT_LONG_NAME.

uint8_t const DIR_ATT_LONG_NAME_MASK = 0X3F

Test mask for long name entry

uint8_t const DIR_ATT_READ_ONLY = 0X01

file is read-only

uint8_t const DIR_ATT_SYSTEM = 0X04

Entry is for a system file

uint8_t const DIR_ATT_VOLUME_ID = 0X08

Directory entry contains the volume label

uint8_t const DIR_NAME_0XE5 = 0X05

escape for name[0] = 0XE5

uint8_t const DIR_NAME_DELETED = 0XE5

name[0] value for entry that is free after being "deleted"

uint8_t const DIR_NAME_FREE = 0X00

name[0] value for entry that is free and no allocated entries follow

uint16_t const FAT16EOC = 0XFFFF

FAT16 end of chain value used by Microsoft.

uint16_t const FAT16EOC_MIN = 0XFFF8

Minimum value for FAT16 EOC. Use to test for EOC.

uint32_t const FAT32EOC = 0X0FFFFFFF
