|
File is not archived. This flag will be set when the file is created or modified. |
|
File contains a subdirectory. |
|
Only these flags are allowed for files and directories. |
|
Hidden file. |
|
Read only file. |
|
System file. |
|
No file, but a volume label. |
|
Allocate the first cluster of a file.
|
|
PHAT file system driver information structure. A pointer to this structure must be passed to NutRegisterDevice() to bind this file system driver to the Nut/OS kernel. An application may then call /verbatim _open("MMC0:1/PHAT0", _O_RDWR | _O_BINARY); /endverbatim to mount partition 1 on the previously registered block device (devMmc0 in this example). |

|
Sector of the directory entry. For the root directory this value is zero, because the root doesn't have any entry in another directory. |
|
First cluster of the parent directory, low word. Our directory entry is located in this cluster. |
