SetResultsHookHREC
- 0
Sets up a hook callback function for recognition results.
HRECHOOK SetResultsHookHREC( HREC hrec, HRCRESULTHOOKPROC lpfnHook )
Parameters
hrec
Module handle of the recognizer library whose results are to be hooked. If hrec is set to NULL, the hook function specified in lpfnHook receives results from the system default recognizer. If hrec is set to SRH_HOOKALL, the hook function receives results for all recognizers
the application has installed, including the system recognizer.
lpfnHook
Address of the hook function.
Return Value
Returns a handle to the installed hook if successful; otherwise, the return
value is NULL. The application must provide this handle when calling UnhookResultsHookHREC to remove the hook.
Comments
An application can set multiple hooks. The system calls the hooks in reverse
order  that is, the most-recently-set hook is called first, then the previous hook,
and so on. If a hook function captures a result, the function that requested the
results returns HRCR_HOOKED to the application.
