This enumeration represents pointers to types of parameters.
Syntax
typedef enum SPEVENTLPARAMTYPE{
SPET_LPARAM_IS_UNDEFINED = 0,
SPET_LPARAM_IS_TOKEN,
SPET_LPARAM_IS_OBJECT,
SPET_LPARAM_IS_POINTER,
SPET_LPARAM_IS_STRING
} SPEVENTLPARAMTYPE;
Elements
- SPET_LPARAM_IS_UNDEFINED
The lParam value in the SPEVENT structure represents an undefined value. For all TTS events, except SPEI_VOICE_CHANGE and SPEI_TTS_BOOKMARK, the parameter type is SPET_LPARAM_IS_UNDEFINED. Possible events are defined for the SPEVENTENUM enumeration.
- SPET_LPARAM_IS_TOKEN
The SPEVENT.lParam value points to an object implementing ISpObjectToken. For example, since the TTS voice change event (SPEI_VOICE_CHANGE) includes a pointer to the object token for the new voice, SPEVENT.lparam is set to SPET_LPARAM_IS_TOKEN.
- SPET_LPARAM_IS_OBJECT
The SPEVENT.lParam value points to an object. For example, since the speech recognition event (SPEI_RECOGNITION) includes a pointer to the recognition result (ISpRecoResult), SPEVENT.lParam is set to SPET_LPARAM_IS_OBJECT.
- SPET_LPARAM_IS_POINTER
The SPEVENT.lParam value represents a memory pointer.
- SPET_LPARAM_IS_STRING
The SPEVENT.lParam value points to a string. For example, since the TTS bookmark event (SPEI_TTS_BOOKMARK) includes a pointer to the bookmark name, SPEVENT.lParam is set to SPET_LPARAM_IS_STRING.
