errno failure with rename RTEMS

Question

I am using the rename function with RTEMS to attempt to rename files. I am setting up a correct error handling and reporting system when i discovered that RTEMS does not seem to be conforming to its own errno reporting guide.

So the function in failure will always return -1. The current example is in a directory </D\> where i have the following:

 </D\LALALA>
 </D\LALALA_2>
 </D\OTHER_DIRECTORY>

I call rename("LALALA_1", "LALALA_2") which works correctly and the folder is renamed. So i know the function works. If i call rename("LALALA", "LALALA_2"), it fails returning -1... which is great, but instead of EEXIST i get errno == -1.

So this looks to be a bug with the RTEMS implementation.

It is not likely that it will ever be fixed.
