This macro casts the specified value to a 64-bit type.
Syntax
SPFEI(
void* SPEI_ord
);
Parameters
- SPEI_ord
[in, out] Pointer to the value. On input, this parameter indicates the value to cast. On output, it indicates the recast value. For a list of the supported types of values, see SPEVENTENUM.
Return Value
No error code is returned.
Remarks
Helper macros related to SPFEI are listed below.
| Macro | Description |
|---|---|
SPFEI_FLAGCHECK |
Retrieves reserved flags for the event interest enumeration. |
SPEI_ALL_EVENTS |
Retrieves all possible event flags. |
SPFEI_ALL_TTS_EVENTS |
Retrieves all possible text-to-speech (TTS) event flags. |
SPFEI_ALL_SR_EVENTS |
Retrieves all possible speech recognition (SR) event flags. |
SAPI uses the SPFEI_FLAGCHECK macro to retrieve flags that must always be included in any event interest. Use of this macro helps developers avoid mistakes by using event interest-related methods with the actual enumeration. See ISpEventSource::SetInterest and ISpRecoContext::SetVoicePurgeEvent.
Example
The following example shows the SPFEI macro used to set the SR event interest.
hr = g_cpRecoCtxt->SetInterest(SPFEI(SPEI_RECOGNITION), SPFEI(SPEI_RECOGNITION));
The following example shows the SPFEI_ALL_SR_EVENTS macro used to set SR event interest in all events. This is an example and not recommended practice.
hr = g_cpRecoCtxt->SetInterest(SPFEI_ALL_SR_EVENTS, SPFEI_ALL_SR_EVENTS);
