disk_status

+

The disk_status function is called to inquire the current drive status.

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

Parameter

+
+
pdrv
+
Physical drive number to identify the target device. Always zero at single drive system.
+
+
+ + +
+

Return Values

+

The current drive status is returned in combination of status flags described below. FatFs refers only STA_NOINIT and STA_PROTECT.

+
+
STA_NOINIT
+
Indicates that the device has not been initialized and not ready to work. This flag is set on system reset, media removal or failure of disk_initialize function. It is cleared on disk_initialize function succeeded. Any media change that occurs asynchronously must be captured and reflect it to the status flags, or auto-mount function will not work correctly. If the system does not support media change detection, application program needs to explicitly re-mount the volume with f_mount function after each media change.
+
STA_NODISK
+
Indicates that no medium in the drive. This is always cleared at fixed disk drive. Note that FatFs does not refer this flag.
+
STA_PROTECT
+
Indicates that the medium is write protected. This is always cleared at the drives without write protect function. Not valid if STA_NODISK is set.
+
+
+ +

Return

+ + -- cgit v1.2.3
