Closing all handles for red_unmount()

[Tuxera-TonyQ]

[Note: This question was originally asked and answered on April 1st, 2020, before the release of Reliance Edge v2.5. This customer was using Reliance Edge v2.4 at the time.]

Hi,

I'm trying to properly unmount Reliance Edge so I can power off my device and format the volume, but in the Developer's Guide it says:

"Before unmounting, this function will wait for any active file system thread to complete by acquiring the FS mutex. The
volume will be marked as unmounted before the FS mutex is released, so subsequent FS threads will possibly block
and then see an error when attempting to access a volume which is unmounting or unmounted. [b]If the volume has open
handles, the unmount will fail.[/b]"

I'm having a hard time trying to manually close every single file and directory beeing used, so I wondered if there are any other ways to use red_unmount() without doing this. If not, are there other ways to format it instead of unmounting it before?

Thanks in advance!

Greetings,

The upcoming Reliance Edge v2.5 release adds a red_umount2() API which has a “force” flag that can be used to automatically close every single file and directory.

/** Force unmount, closing all open handles. */
#define RED_UMOUNT_FORCE 0x00000001U

int32_t red_umount2(
const char *pszVolume,
uint32_t ulFlags);

In Reliance Edge v2.4, there isn’t a way to unmount without closing the handles.
