- inputDevice is the id of the device used for input (see PaDeviceID above.)
- inputDevice may be paNoDevice to indicate that an input device is not required.
- 
- numInputChannels is the number of channels of sound to be delivered to the
- callback. It can range from 1 to the value of maxInputChannels in the
- PaDeviceInfo record for the device specified by the inputDevice parameter.
- If inputDevice is paNoDevice numInputChannels is ignored.
- 
- inputSampleFormat is the sample format of inputBuffer provided to the callback
- function. inputSampleFormat may be any of the formats described by the
- PaSampleFormat enumeration (see above). PortAudio guarantees support for
- the device's native formats (nativeSampleFormats in the device info record)
- and additionally 16 and 32 bit integer and 32 bit floating point formats.
- Support for other formats is implementation defined.
- 
- inputDriverInfo is a pointer to an optional driver specific data structure
- containing additional information for device setup or stream processing.
- inputDriverInfo is never required for correct operation. If not used
- inputDriverInfo should be NULL.
- 
- outputDevice is the id of the device used for output (see PaDeviceID above.)
- outputDevice may be paNoDevice to indicate that an output device is not required.
- 
- numOutputChannels is the number of channels of sound to be supplied by the

- outputDriverInfo is a pointer to an optional driver specific data structure
- containing additional information for device setup or stream processing.
- outputDriverInfo is never required for correct operation. If not used
- outputDriverInfo should be NULL.
- 
- sampleRate is the desired sampleRate. For full-duplex streams it is the
- sample rate for both input and output
- 
- framesPerBuffer is the length in sample frames of all internal sample buffers
- used for communication with platform specific audio routines. Wherever
- possible this corresponds to the framesPerBuffer parameter passed to the
- callback function.
- 
- numberOfBuffers is the number of buffers used for multibuffered communication
- with the platform specific audio routines. If you pass zero, then an optimum
- value will be chosen for you internally. This parameter is provided only
- as a guide - and does not imply that an implementation must use multibuffered
- i/o when reliable double buffering is available (such as SndPlayDoubleBuffer()
- on the Macintosh.)
- 
- streamFlags may contain a combination of flags ORed together.
- These flags modify the behaviour of the streaming process. Some flags may only
- be relevant to certain buffer formats.
- 
- callback is a pointer to a client supplied function that is responsible
- for processing and filling input and output buffers (see above for details.)
- 
- userData is a client supplied pointer which is passed to the callback
- function. It could for example, contain a pointer to instance data necessary
- for processing the audio buffers.

- Upon success Pa_OpenStream() returns PaNoError and places a pointer to a

- 
- inputDevice is the id of the device used for input (see PaDeviceID above.)
- inputDevice may be paNoDevice to indicate that an input device is not required.
- 
- numInputChannels is the number of channels of sound to be delivered to the
- callback. It can range from 1 to the value of maxInputChannels in the
- PaDeviceInfo record for the device specified by the inputDevice parameter.
- If inputDevice is paNoDevice numInputChannels is ignored.
- 
- inputSampleFormat is the sample format of inputBuffer provided to the callback
- function. inputSampleFormat may be any of the formats described by the
- PaSampleFormat enumeration (see above). PortAudio guarantees support for
- the device's native formats (nativeSampleFormats in the device info record)
- and additionally 16 and 32 bit integer and 32 bit floating point formats.
- Support for other formats is implementation defined.
- 
- inputDriverInfo is a pointer to an optional driver specific data structure
- containing additional information for device setup or stream processing.
- inputDriverInfo is never required for correct operation. If not used
- inputDriverInfo should be NULL.
- 
- outputDevice is the id of the device used for output (see PaDeviceID above.)
- outputDevice may be paNoDevice to indicate that an output device is not required.
- 
- numOutputChannels is the number of channels of sound to be supplied by the
- callback. See the definition of numInputChannels above for more details.
- 
- outputSampleFormat is the sample format of the outputBuffer filled by the
- callback function. See the definition of inputSampleFormat above for more
- details.
- 
- outputDriverInfo is a pointer to an optional driver specific data structure
- containing additional information for device setup or stream processing.
- outputDriverInfo is never required for correct operation. If not used
- outputDriverInfo should be NULL.
- 
- sampleRate is the desired sampleRate. For full-duplex streams it is the
- sample rate for both input and output
- 
- framesPerBuffer is the length in sample frames of all internal sample buffers
- used for communication with platform specific audio routines. Wherever
- possible this corresponds to the framesPerBuffer parameter passed to the
- callback function.
- 
- numberOfBuffers is the number of buffers used for multibuffered communication
- with the platform specific audio routines. If you pass zero, then an optimum
- value will be chosen for you internally. This parameter is provided only
- as a guide - and does not imply that an implementation must use multibuffered
- i/o when reliable double buffering is available (such as SndPlayDoubleBuffer()
- on the Macintosh.)
- 
- streamFlags may contain a combination of flags ORed together.
- These flags modify the behaviour of the streaming process. Some flags may only
- be relevant to certain buffer formats.
- 
- callback is a pointer to a client supplied function that is responsible
- for processing and filling input and output buffers (see above for details.)
- 
- userData is a client supplied pointer which is passed to the callback
- function. It could for example, contain a pointer to instance data necessary
- for processing the audio buffers.
- 
- return value:
- Upon success Pa_OpenStream() returns PaNoError and places a pointer to a
- valid PortAudioStream in the stream argument. The stream is inactive (stopped).
- If a call to Pa_OpenStream() fails a non-zero error code is returned (see
- PaError above) and the value of stream is invalid.
