enum epicsSocketSystemCallInterruptMechanismQueryInfo

Enum specifying how to interrupt a blocking socket system call.

This enum specifies how to interrupt a blocking socket system call. Fortunately, on most systems the combination of a shutdown of both directions and/or a signal is sufficent to interrupt a blocking send, receive, or connect call. For odd ball systems this is stubbed out in the osi area.

Values:

enumerator esscimqi_socketCloseRequired

Calling close() required to interrupt.

enumerator esscimqi_socketBothShutdownRequired

calling shutdown() for both read and write required to interrupt

enumerator esscimqi_socketSigAlarmRequired

NO LONGER USED/SUPPORTED.
