Open System Services System Calls Reference Manual (G06.29+, H06.08+, J06.03+)

System Functions (s and S) spt_readvx(2)
[EINTR] An spt_readvx() operation was interrupted by a signal before any data arrived.
[EINVAL] One of these conditions occurred:
• The sum of the iov_len values in the iov array was negative or
overflowed a data item of type ssize_t.
• The value of the iov_count parameter was less than or equal to 0 (zero)
or greater than IOV_MAX.
[EIO] One of these conditions occurred:
• The process is a member of a background process group attempting to
read from its controlling terminal, the process is ignoring or blocking the
SIGTTIN signal, or the process group 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.
[EISDIR] An spt_readvx() operation was attempted against a directory.
[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 node, but communication with
the remote node has been lost.
[ENOTCONN] The socket is no longer connected to a peer socket.
[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.
• 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 for use of the file
descriptor.
The file descriptor specified by the filedes parameter can only be closed.
For all other error conditions, errno is set to the appropriate Guardian file-system error number.
For more information about a specific Guardian file-system error, see the Guardian Procedure
Errors and Messages Manual.
