SPFEI
SPFEI casts a specified value into a 64-bit type.
For a list of the supported SPEI_ord event types, see SPEVENTENUM
Found in: sapi.idl
SPFEI(
void *SPEI_ord
);
Parameters
- SPEI_ord
- [in, out] The value to re-cast. The new value is passed back.
Return values
No error code is returned.Related Helper Macros
| Macro | Description |
|---|---|
| SPFEI_FLAGCHECK | Retrieves reserved flags for the event interest enum. |
| SPEI_ALL_EVENTS | Retrieves all possible events flags. |
| SPFEI_ALL_TTS_EVENTS | Retrieves all possible TTS event flags. |
| SPFEI_ALL_SR_EVENTS | Retrieves all possible SR event flags. |
Remarks
The SPFEI_FLAGCHECK macro retrieves the flags that must always be included in any event interest. SAPI uses the SPFEI_FLAGCHECK macro to help developers avoid mistakes by using event interest related methods (see ISpEventSource::SetInterest and ISpRecoContext::SetVoicePurgeEvent) with the actual enumeration instead of the SPFEI() macro.
Example
Here is an example of the SPFEI macro used to set SR event interest
hr = g_cpRecoCtxt->SetInterest(SPFEI(SPEI_RECOGNITION), SPFEI(SPEI_RECOGNITION));
Here is an example of the SPFEI_ALL_SR_EVENTS macro used to set SR event interest in all events. Note this is an example and not recommended practice.
hr = g_cpRecoCtxt->SetInterest(SPFEI_ALL_SR_EVENTS, SPFEI_ALL_SR_EVENTS);
