disk_status

+

The disk_status function returns the current disk status.

+
+DSTATUS disk_status (
+  BYTE pdrv     /* [IN] Physical drive number */
+);
+
+
+ +
+

Parameter

+
+
pdrv
+
Physical drive number to identify the target device.
+
+
+ + +
+

Return Values

+

The disk status is returned in combination of following flags. FatFs refers only STA_NOINIT and STA_PROTECT.

+
+
STA_NOINIT
+
Indicates that the device is not initialized. This flag is set on system reset, media removal or failure of disk_initialize() function. It is cleared on disk_initialize() function succeeded. Media change that occurs asynchronously must be captured and reflect it to the status flags, or auto-mount feature will not work correctly. When media change detection feature is not supported, application program needs to de-initialize the file system object with f_mount() function after the media change.
+
STA_NODISK
+
Indicates that no medium in the drive. This is always cleared on fixed disk drive. Note that FatFs does not refer this flag.
+
STA_PROTECT
+
Indicates that the medium is write protected. This is always cleared on the drives without write protect feature. Not valid while no medium in the drive.
+
+
+ +

Return

+ + -- cgit v1.2.3
