Synopsis

.. c:macro:: FE_READ_UNCORRECTED_BLOCKS

int ioctl(int fd, FE_READ_UNCORRECTED_BLOCKS, uint32_t *ublocks)

Arguments

fd File descriptor returned by :c:func:open().

ublocks The total number of uncorrected blocks seen by the driver so far.

Description

This ioctl call returns the number of uncorrected blocks detected by the device driver during its lifetime. For meaningful measurements, the increment in block count during a specific time interval should be calculated. For this command, read-only access to the device is sufficient.

Return Value

On success 0 is returned.

On error -1 is returned, and the errno variable is set appropriately.

Generic error codes are described at the :ref:Generic Error Codes <gen-errors> chapter.
