when i trying to create directory with name same as disk mount point
it will successfully create directory with empty name on the disk :
Yes, we were aware of this. After creation there will be a physical directory “
“, and a logical (mounted) directory with the same name.
I mounted usb flash drive to point “/usb”. Mount was successful,
i can see files and folders on the drive.
Indeed, when you access
, the logical ( mounted ) directory will prevail.
Then for test purposes i call ff_mkdir(“/usb”) awaiting that it return
me some error, for example
FF_ERR_DIR_OBJECT_EXISTS, but it was successful !
You’re right, formally this should be checked for.
Looking in flash disk drive i see new directory whith empty name that
can not be entered or deleted.
There is indeed a bit of a problem here, also FTP shows two directories: a virtual one, and a physical directory on an SD-card.
Only formatting whole drive helps remove it ))
Not true. When using the
functions, the directory can be emptied and removed.
As you have probably seen, the
are aware of the mounted directories.
functions have an I/O manager as a parameter, and these functions are working on physical drives only.
Is it normal ?
We always seek a balance between simplicity and completeness, correctness.
I was aware that a physical directory can be created, while a mounted directory already exists.
But what should the library say if you mount a drive on “/usr”, while a directory with that name already exists. Do you want the mount to fail?
Personally, I think that the physical directory should be ignored by the “ff_” functions.
And yes, a call to
Some work has to be done here.
