|
|
// The Generic Scripting Resource uses a separate working thread to do all
|
|
// calls into the Script. This is because the Scripting Host Engines require
|
|
// only the creating thread to call them (remember, scripting is designed
|
|
// to be used in a user mode application where usually the UI thread runs
|
|
// the script). To make this possible, we serialize the threads entering the
|
|
// the script using a user-mode spinlock (m_lockSerialize). We then use two events
|
|
// to signal the "worker thread" (m_EventWait) and to signal when the "worker
|
|
// thread" has completed the task (m_EventDone).
|
|
//
|
|
// LooksAlive is implemented by returning the last result of a LooksAlive. It
|
|
// will start the "worker thread" doing the LooksAlive, but not wait for the
|
|
// thread to return the result. Because of this, all the other threads must
|
|
// make sure that the "Done Event" (m_EventDone) is signalled before writing
|
|
// into the common buffers (m_msg and m_hr).
