Is it possible that framesRead == framesToRead when hitting the end of a stream?

[Raildex]

I am using ma_decoder_read_pcm_frames within a callback of my audio system.

Is it possible that the function returns framesRead == framesToRead even when hitting the end of stream?

I am using miniaudio to feed the frames to XAudio2, which expects the last audio buffer of a stream to have the flag XAUDIO2_END_OF_STREAM.

When I call ma_decoder_read_pcm_frames again after such a circumstance, It will just return framesRead == 0 and return MA_AT_END, but in that case, I can't set the flag for XAudio2, because I can't submit a buffer of length zero.

Am I misunderstanding the usage of this function here?

You're out of luck there. The rule used by miniaudio is MA_AT_END will only be returned when framesRead == 0. It should never return MA_AT_END if the number of frames read is more than 0. That rule is used globally throughout miniaudio, not just ma_decoder.
