[ENFILE] One of these conditions exists:
• The maximum number of file descriptors of this file type (socket, pipe,
etc.) for this processor are already open.
• The limit for open file descriptors of this file type has not been exceeded,
but the maximum number of all file descriptors for this processor are
already open.
[ENOMEM] There was insufficient memory available to complete the operation.
[ENOROOT] The function was called while the root fileset (fileset 0) was not available.
[EOSSNOTRUNNING]
The function was called while a required system process was not running.
For all other error conditions, errno is set to the appropriate Guardian file-system error number.
