Function Documentation

HWAVEIN PaWinMME_GetStreamInputHandle	(	PaStream *	stream,
		int	handleIndex
	)

Retrieve a wave in handle used by a PortAudio WinMME stream.

Parameters:

	stream	The stream to query.
	handleIndex	The zero based index of the wave in handle to retrieve. This should be in the range [0, PaWinMME_GetStreamInputHandle(stream)-1].

Returns:

A valid wave in handle, or NULL if an error occurred.

See also:

PaWinMME_GetStreamInputHandle

int PaWinMME_GetStreamInputHandleCount

(

PaStream *

stream

)

Retrieve the number of wave in handles used by a PortAudio WinMME stream. Returns zero if the stream is output only.

Returns:

A non-negative value indicating the number of wave in handles or, a PaErrorCode (which are always negative) if PortAudio is not initialized or an error is encountered.

PaWinMME_GetStreamInputHandle

HWAVEOUT PaWinMME_GetStreamOutputHandle	(	PaStream *	stream,
		int	handleIndex
	)

Retrieve a wave out handle used by a PortAudio WinMME stream.

Parameters:

	stream	The stream to query.
	handleIndex	The zero based index of the wave out handle to retrieve. This should be in the range [0, PaWinMME_GetStreamOutputHandleCount(stream)-1].

Returns:

A valid wave out handle, or NULL if an error occurred.

PaWinMME_GetStreamOutputHandleCount

int PaWinMME_GetStreamOutputHandleCount

(

PaStream *

stream

)

Retrieve the number of wave out handles used by a PortAudio WinMME stream. Returns zero if the stream is input only.

Returns:

A non-negative value indicating the number of wave out handles or, a PaErrorCode (which are always negative) if PortAudio is not initialized or an error is encountered.
