VTCPD Features User Manual
•A new GET operation is received by the daemon.
• The application unbinds from VMST (exits or crashes).
• Host connection is lost. In this case, all applications currently using the link will
receive condition hostdown.
An application can also receive a condition:
• hostdown, if at the time of the request there are no connections to the host at all,
or if the specified connection is not established (or lost).
• hostup, if command option -m u is specified and the first link to the host is
established. It allows applications to block on DELAY waiting for a hostup
condition instead of looping indefinitely when host computer goes down. This
condition is not returned to applications (by default).
• getfail, if specified pool or common pool is full. Optionally, all requests may be
queued by the VTCPD daemon until there is an available slot.
• invreq, if RECEIVE request is sent prior to SEND (that is, no message ID is
available) and the pool size is greater then 1 (there is no Message ID matching if
the pools size is 1).
• invreq, if the specified connection doesn't fall into (1-maxlinks) range
• invreq, if the string in SEND message is not long enough to accommodate the
Message ID.
• inf, if the string received from the host is not large enough to accommodate the
message ID.
• hostfail, if the daemon cannot allocate memory or is experiencing some other
internal problems.
