Open System Services System Calls Reference Manual (G06.28+, H06.05+)

System Functions (s and S) spt_readvx(2)
[EFILEBAD] An attempt was made to read from a Guardian EDIT
file (a file in /G
with file code 101) with a corrupted internal structure.
[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 Guar-
dian environment.
[ENETDOWN]
The filedes parameter specifies a file on a remote node, but communica-
tion 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 dur-
ing 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
