System Functions (w) writev(2)
[EGUARDIANLOCKED]
A writev() operation was attempted to a file in the Guardian file system (that is,
a file in /G) that is locked.
[EINTR] A writev() operation was interrupted by a signal before any data was written.
[EINVAL] One of these conditions occurred:
• The file position pointer associated with the file specified by the filedes
parameter was negative.
• The value of the iov_count parameter was less than or equal to 0 (zero),
or greater than IOV_MAX.
• One of the iov_len values in the iov array was negative or overflowed a
data item of type ssize_t.
• The sum of the iov_len values in the iov array overflowed an integer.
[EIO] One of these conditions occurred:
• The process is a member of a background process group attempting to
write to its controlling terminal, the TOSTOP flag is set, the process is
neither ignoring nor blocking the SIGTTOU signal, and the process
group of the process is orphaned.
• A physical I/O 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. Data might have been lost during a transfer.
[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 com-
munication with the remote node has been lost.
[ENOSPC] No free space is left on the fileset containing the file.
[ENOTCONN] An attempt was made to write to a socket that is not connected to a peer socket.
[ENXIO] One of these conditions occurred:
• The device associated with the file descriptor specified by the filedes
parameter is a block special device or character special file, and the file
pointer is out of range.
• No existing device is associated with the file descriptor specified by the
filedes parameter.
[EPIPE] One of these conditions occurred:
• An attempt was made to write to a pipe or FIFO file that is not open for
reading by any process. A SIGPIPE signal is sent if the process is run-
ning in the OSS environment.
• An attempt was made to write to a pipe that has only one end open.
