Re: any way to learn if an event is already scheduled?

[Sudheer Vinukonda]

AFAIK, there isn't a way to identify if a hook is already added, but, you can 
certainly block the call back being run more than once, but using either 
TSContDataSet() (within the same plugin) or TSHttpTxnArgSet() (across plugins).

Hi folks,

Is there a way (preferably plugin visible public API) to learn if there is
an event pending for some arbitrary hook given a transaction?

For example, if one was to invoke:
    TSHttpHookAdd(TS_HTTP_TXN_CLOSE_HOOK, cont);
OR
    TSHttpTxnHookAdd(txnp, TS_HTTP_TXN_CLOSE_HOOK, cont);

is there a way to learn if there is already pending TS_EVENT_HTTP_TXN_CLOSE
event for that particular transaction before or after adding a hook? Or
even, when handling the event.

I hope my question makes sense. I would appreciate anyone's assistance.
