Member Variable Description
NOTE
No enumerated values are defined as the return values of the following callbacks. In the current version, no processing specific to the return value is provided. To support expansion in later versions, the default value 0 is used.
OH_AudioCapturer_OnError
int32_t (*OH_AudioCapturer_Callbacks_Struct::OH_AudioCapturer_OnError)(OH_AudioCapturer *capturer, void *userData, OH_AudioStream_Result error)
Description
Defines a function pointer to the callback function used to process audio recording errors.
OH_AudioCapturer_OnInterruptEvent
int32_t (*OH_AudioCapturer_Callbacks_Struct::OH_AudioCapturer_OnInterruptEvent)(OH_AudioCapturer *capturer, void *userData, OH_AudioInterrupt_ForceType type, OH_AudioInterrupt_Hint hint)
Description
Defines a function pointer to the callback function used to process audio recording interruption events.
OH_AudioCapturer_OnReadData
int32_t (*OH_AudioCapturer_Callbacks_Struct::OH_AudioCapturer_OnReadData)(OH_AudioCapturer *capturer, void *userData, void *buffer, int32_t lenth)
Description
Defines a function pointer to the callback function used to read audio data.
OH_AudioCapturer_OnStreamEvent
int32_t (*OH_AudioCapturer_Callbacks_Struct::OH_AudioCapturer_OnStreamEvent)(OH_AudioCapturer *capturer, void *userData, OH_AudioStream_Event event)
