Guardian Native C Library Calls (f) fpathconf(3)
• The filedes parameter specifies an AF_INET or AF_INET6 socket or an
unbound AF_UNIX socket.
[EIO] An input or output error occurred. The device holding the file might be in the
down state, or both processors that provide access to the device might have
failed.
[EISGUARDIAN]
The value used for the filedes parameter is appropriate only in the Guardian
environment.
[ENETDOWN]
The filedes parameter specifies a file on a remote HP NonStop node but commun-
ication with the remote node has been lost.
[ENOROOT] The program attempted an operation while the root fileset was unavailable.
[ENXIO] An invalid device or address was specified during an input or output operation
on a special file. One of the following events occurred:
• A device was specified that does not exist, or a request was made beyond
the limits of the device.
• The fileset containing the requestor’s current working directory or root
directory is not mounted. This error can occur after failure and restart of
an OSS name server until the fileset has been repaired and remounted.
[EWRONGID] One of the following conditions occurred:
• The process attempted an operation through an operating system
input/output process (such as a terminal server process) that has failed or
is in the down state.
• The processor for the disk process of the specified file failed during an
input or output operation, and takeover by the backup process occurred.
• The open file descriptor has migrated to a new processor but the new
processor lacks a resource or system process needed to use the file
descriptor.
The file descriptor specified by the filedes parameter can only be closed.
