Hi,

If one process has opened a file exclusively or has locked a part of the file,
then other processes, which try to open this file, will get either the error
code ERROR_SHARING_VIOLATION or the error code ERROR_LOCK_VIOLATION.
Both error codes are mapped to EACCES in errno.cc. This doesn't reflect the
real situation.
So I want to suggest the following change to errno.cc:

Change the mapping of the above error codes to ETXTBSY.

The patch is attached.

Regards,
Corinna
