System Functions (w) writev(2)
One of the iov_len values in the iov array was negative or overowed a
data item of type ssize_t.
The sum of the iov_len values in the iov array overowed 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 ag 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 le 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 ledes parameter is appropriate only in the Guardian
environment.
[ENETDOWN]
The ledes parameter species a le on a remote HP NonStop node, but com-
munication with the remote node has been lost.
[ENOSPC] No free space is left on the leset containing the le.
[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 le descriptor specied by the ledes
parameter is a block special device or character special le, and the le
pointer is out of range.
No existing device is associated with the le descriptor specied by the
ledes parameter.
[EPIPE] One of these conditions occurred:
An attempt was made to write to a pipe or FIFO le 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.
An attempt was made to write to a socket that is shut down or closed.
[ETIMEDOUT]
Data transmission on the socket timed out.
[EWRONGID] One of these conditions occurred:
The process attempted an input or output operation through an operating
system input/output process (such as a terminal server process) that has
failed or is in the down state.
