Filesystem operations with RTEMS

[Mohammed Khoory]

Hi,

I have set up a RAMDisk on RTEMS 4.10.2 and formatted it with dosfs, then
mounted it in a specific address. I'm now trying to do two operations on
this active filesystem:
1. I have an open file in this filesystem, represented in C code as a file
descriptor int, and I'm trying to get the pathname of this file descriptor.
2. I would like to get the amount of free space on this filesystem.

Is there any way I can do either of those?

Thanks,
Mohammed Khoory
