The session with the shell ended because of an unexpected
I/O error. Function = tcflush(), file descriptor = number,
terminal name = 'string', return value = number,
errno = number (X'hexnum'),
reason code = hexnum, message = 'string'
Explanation
An I/O error occurred when trying to flush data
that was queued for the pseudo-TTY. This error caused the session
with the z/OS shell to
end.
In the message text:
- file descriptor = number
- The file descriptor that was being used when this error occurred.
- terminal name = 'string'
- The name of the pseudo-TTY that was being used when this error
occurred.
- return value = number
- The return value reported by the system for this error.
- errno = number (X'hexnum')
- The errno value returned by the system for this error. For more
information about this errno value, see z/OS XL C/C++ Runtime Library Reference.
If errno = 0, no errno information is available from the system for
this error.
- reason code = hexnum
- The reason code returned by the system for this error. For more
information about this reason code, see z/OS UNIX System Services Programming: Assembler Callable Services Reference.
- message = 'string'
- A system error message that describes this error as reported by
errno. If errno = 0, this message is not meaningful.
System programmer response
Make sure that TSO/E commands used
while OMVS is switched to TSO/E do not use any file descriptors that
were opened by the OMVS command.
User response
If this error occurred shortly after you switched
to TSO/E and then returned to the z/OS shell, the
TSO/E commands that were invoked may have caused this error. Contact
the system programmer with this message number and the variable information
displayed in the message.
